Former sumo champion Koji Kitao was expelled from New Japan Pro-Wrestling in 1990 for verbally attacking Riki Choshu (a famous backstage troublemaker himself) with an ethnic slurnote Choshu is Korean. Not only that, he was later released from Super World of Sports for crashing a match against John Tenta and screaming to the crowd that wrestling was fake.
Sherri Martel's back problems led to her getting hooked on oxycodone, or "hillbilly heroin". In 1993, Vince McMahon summoned her to his office and informed her that her services were no longer required. WCW was a bit more accommodating, even allowing Sherri to take time off for detox, but in 2000 she relapsed and was released for good. She and Chris Benoit died with 2 weeks of each other in June of 2007. Both wrestlers had a history of being over-prescribed pain meds (by the same sports physician, no less).
Paul Roma was told to make the young upstart Alex Wright look good in their match at WCW SuperBrawl V, February 19, 1995, en route to losing the match. Roma instead no-sold Wright's offense, mocked his goofy dance to a Face reaction despite the fact that Roma was the Heel here, and actually kicked out of Wright's schoolboy rollup pin attempt, though the ref counted to three anyway. WCW fired Roma after this and he has only ever been seen in small independents ever since.
Bull Nakano was released from the WWF in 1995 for being caught in possession of cocaine. She later went on to wrestle in WCW for a few years before the program shut down.
CMLL stripped Reina Jubuki of its World Women's title in 1995 after she used their willingness to let her compete elsewhere without her mask to fill two slots in the WCW Monday Nitro Womens title tournament with the Jubuki gimmick and as Akira Hokuto. Worse for Hokuto, WCW didn't have nearly as much interest as CMLL in actually doing anything with its women's title. (An alternate view is that CMLL was more displeased with WCW's AAA deal than anything Hokuto did herself)
La Tigresa's five year reign as WWC women's champion ended in 1998 after she was arrested for trying to smuggle heroin into the Puerto Rico State Penitentiary.
Cathy Dingman's short lived tenure in WWE as 'BB Bush' was short lived because she was discovered having an affair with the married Bob Holly in 1999.
Eddie Guerrero was arrested for DUI in 2001 and released by WWE; five months passed before he returned to WWE. Having dealt with many of his personal demons in that period, Eddie returned to enjoy the greatest success of his career (up until his unexpected death in 2005).
Curt Hennig was released from the WWE in May 2002 for his role in the "Plane Ride from Hell", in which he got into a fight with Brock Lesnar on the plane.
A contestant on the third season of WWE Tough Enough in 2002, Lisa, was cut from the competition after having a psychotic breakdown, breaking into the hidden camera room and climbing onto the roof of the house. She was hospitalised but fled when her parents came to check her out, and she managed to have an entire wing of a local airport shut down while people tried to find her. Her fellow contestants (and by extension the audience) were told she left because she decided wrestling wasn't the right career for her.
Teddy Hart, who became the youngest man to ever get a WWE developmental deal in 1998, has been fired and blacklisted from several companies due to his prima donna attitude that makes him a pain to work with backstage, and the fact that he's such an Attention Whore and Spot Monkey that he'll even refuse to go through with previously agreed finishes or the script (where applicable) and show off with insane high-flying moves that put himself and his opponents in danger. That developmental deal lasted four years until he was released from WWE for "attitude problems" in 2002 (though he got two more WWE developmental deals in 2005 and 2006). He was released from Ring of Honorand TNA in 2004 after Sabu had to separate him and CM Punk (he'd make a one night ROH return in 2009 and be offered a TNA return in 2016). He pisses off so many people that some companies (such as AAA in 2010, before he returned as part of los Perros Del Mal at Triplemania XX) admit to firing him out of fear that some coworkers will attempt to murder him.
Jeff Hardy, Mr. Fanservice and an expert at working the crowd (though with increasingly poor workmanship in his actual wrestling), originally lost his WWE job in 2003 due to his drug abuse; he was hired a year later by TNA (a company with a notably less stringent drug-testing policy). He then lost his job with TNA due to no-showing a number of events and then was rehired by WWE a few months later. He blitzed through several Wellness policy strikes before leaving to "heal from injuries", not coincidentally around the time he was arrested for steroid and prescription pill trafficking. TNA rehired him in January 2010, and he held it together for about 9 months before falling off the wagon, eventually culminating at the 2011 Victory Road PPV where Jeff went out to wrestle Sting while stoned out of his gourd. Hardy had to make a public apology when he returned and TNA told him that it would be his last chance.
Ring of Honor has lost both of its founders to such events. Gabe 'Jimmy Bowers' Sapolsky for booking an exceptionally tasteless and widely mocked angle, was simply him lapsing at his job but Rob 'Fun Athletic Guy' Feinstein was caught trying to get an underaged boy to consent in 2004. Among wrestlers not named Teddy Hart, Adam Pearce was effectively banned from the promotion for telling a merchandise agent picked up by consequence of the Sinclair purchase that he wanted to beat the piss out of him.
A family member of Torrie Wilson's fell ill suddenly and she had to immediately go home to see them. Through sheer bad luck she was unable to get a hold of anyone in the office to notify them. She ended up missing a Raw and a PPV that she was advertised for and was fired by the company. However she was rehired back a few days later. She theorised that it would have been a PR disaster for them if word got out.
Juventud Guerrera was fired from WWE apparently because dancing on a car while high in 2006 was bad for their publicity and by AAA in 2009 after getting in a locker room fight when he found someone had taken a dump in his bagnote Guerrera insists it was Konnan while Konnan said it was X Pac, but thought it was funny either way. AAA did take him back though, because it was easy to understand why he did so.
Kurt Angle was released from the WWE in 2006 allegedly for his refusal to go into rehab.
While he wasn't fired for it, getting busted for marijuana possession in 2007 led then "ECW" and WWE Champion Rob Van Dam to drop both of those titles in two days (one on Raw, the other on ECW the next night) before serving out his sixty-day Wellness suspension.
Dr. Wagner Jr and L.A. Park were fired by CMLL after their 75th Anniversary show in September of 2008 for going overboard during their match, though Wagner claimed it was due him criticizing CMLL in the press and lead a 200 man protest march for everyone who felt mistreated by their bosses. Seven years later, both were advertised for CMLL's 82nd Anniversary show in September of 2015 and were an important part of the build up to it but L.A. Park ended up being removed from the card and fired after using what CMLL deemed excessive profanity during a promo which consisted of him insulting the arena Mexico fans.
Serena, of CM Punk's Straight Edge Society, was let go in 2010 for excessive partying and drinking in public. So not only was she becoming a detriment to WWE's image and acting unprofessionally, she was contradicting the character she played. However, take in mind that weeks earlier, Serena helped save CM Punk from Kane's wrath by the showing the only thing that would help clear his name: footage of her relapse. It just was legitimate this time. WWE brought her back in 2017 for a spot in the WWE Mae Young Classic.
A subversion happened with Daniel Bryan in 2010. During the segment where the Nexus debuted, several sponsors complained about a part where Bryan choked ring announcer Justin Roberts with his tie, as it brought back memories of the Chris Benoit murders. According to Roberts's autobiography, Vince McMahon reportedly loved it but publicly released Bryan to appease the sponsors - with the full intention of hiring him back a few months later.
7 ft Isis the Amazon was advertised for the third season of NXT as "Aloisa" in 2010 but was cut from the show after it was found that she had done erotic fetish photos online. She wasn't released however until she actively started complaining about it to any interviewer who asked.
In August 2010, Taryn Terrell (a.k.a. former WWE Diva Tiffany) was fired after getting arrested for assaulting her husband Drew McIntyre.
While not fired per se, the name Nick Gage, who was highly decorated in CZW, would become fodder for angles after fans of the promotion identified him as an attempted bank robber to the authorities in December of 2010, leading to his arrest. Drew Gulak would name him and several others who left CZW for various legal related problems during his "Campaign For A Better Combat Zone".
Lince Dorado would be fired from Chikara in 2011, either for appearing in public without his mask or for no showing one too many events, former story being more popular.
Sometimes wrestler, sometimes booker NOSAWA Rongai was fired from All Japan Pro Wrestling in 2011 after attacking a taxi driver, stealing the car and driving it without license, all while thoroughly drunk. This hit to his reputation no doubt "helped" the latter Sugi incident.
Famed Japanese high-flyer Takuya Sugi had his career terminated in 2012 after taking part in the NOSAWA drug scandal, in which he planted marijuana in NOSAWA Rongai's baggages to get him in jail in exchange for a full time contract in AAA. This is a particularly ugly example, not only due to its nasty nature, but also because Sugi himself was the one who revealed his own role in the incident out of guilt, and because the AAA executive who proposed him the treat, Masahiro Hayashi, went seemingly unpunished for his part. Sugi would return to the ring, but it wouldn't be until three years later that he didn't use very covert identities while doing so, and he didn't seem to have a full-fledged return unil 2017.
AW, the manager for the Prime Time Players was released after he made an off color reference to the Kobe Bryant rape case (which was aired live on Raw no less) in 2012, although he had made several other statements in the weeks leading up to it (and The Big Show had referenced the same incident on Smackdown, a pre taped show that could easily remove them).
Kelly Kelly invoked this in late 2012. She had wanted to take a hiatus from the company for a while and disappeared for a few months, before making a couple of reappearances. However she wished to leave altogether due to nagging injuries and the office refused to release her. She responded by taking part in a very risque photo shoot for a calendar. After refusing to take some of the photos down from her website, the office released her.
Ivelisse Vélez was abruptly let go in 2012 and the reason was said to be "attitude problems" - and a rumour went around that it was because she had been acting very arrogant and believing she would be on the main roster soon. She denied these claims and later said that she had spoken up against trainer Bill DeMott and his abuse of trainees. She claimed that she was released to be made an example of.
Double Subverted with Emma, who was released by WWE in 2014 after she was arrested for shoplifting (though, in reality, it was less deliberate shoplifting and more having difficulties with a self-checkout machine.) As it happens, this is a literal example — as is the case in most shoplifting arrests, she was charged with misdemeanor petty theft. Almost immediately, it became clear that fans and wrestling sites alike already had their claws out ready to defend her, seeing as she was fired for what was clearly an honest mistake while other superstars have done far worse and are still with the company. The notoriously PR-conscious WWE, seeing an oncoming wave of bad publicity and likely wanting to keep their sole Australian on the roster for an upcoming tour of the country, rehired her roughly an hour after her release was announced. However, she was released for good in late 2017 for using Twitter to complain about being underutilized on TV.
Japanese junior heavyweight lgend Koji Kanemoto was fired and blacklisted from WRESTLE-1 in 2014 when he got into a fight with a fan after a match, causing a brawl that needed the police to be shut down. According to Kanemoto, the fan turned angry when Koji didn't want to sign an autograph and attacked him.
A really baffling case in 2014 was Brian Blaze's absence from PCW Sacred Ground: Chapter Five, where he was to be part of the Big F'N Deal vs Washing Bullets Tag Team match that was four consecutive years in the making. Neither the fans nor the staff rejected Blaze because of his legal trouble, pretty much everyone at PCW wanted him on the show, Blaze physically couldn't make it because he was being held in prison for the past five months. Who wanted him shut away wasn't clear as the the police officer who arrested Blaze said he didn't want to and went so far as to offer to testify on Blaze's behalf in court. The court initially dismissed Blaze's lawyer but then claimed that was an accident, after Blaze had been found guilty. As Blaze had absolutely no criminal record, it would have been the perfect angle to garner sympathy for a babyface except was a legitimate occurrence ruining Blaze's life, and rather than targeting him specifically he apparently was "just" the first scapegoat that could be found Brian resembled a wanted criminal evading police and had borrowed a vehicle similar enough to one used in armed robbery for a thorough investigation and proper court case to be deemed unnecessary. The silver lining was that Brian Blaze's merchandise sold out at Sacred Ground and his innocence was proven with the funds raised, but it was a shocking example the respect pro wrestlers no longer got from the general public.(there would have been riots if someone tried with, say, Junkyard Dog)
Yoshiko was suspended indefinitely from Wonder Ring STARDOM for going into business for herself and attacking Act Yasukawa for real during their Feb. 22, 2015 match, beating Yasukawa to a bloody pulp, breaking her nose, cheek and orbital bone around her surgically repaired eye.
In July 2015, Hulk Hogan was released from the WWE after a tape featuring him making racist comments was leaked to the public. Even more so, it was a sex tape that he was suing to try to prevent it from being released. The tape itself would eventually become this for Gawker Media, as Hogan subsequently sued the company into bankruptcy, and Univision, upon purchase of its assets, stated that all of its divisions except Gawker would continue to operate.
On August 31, 2015, the girlfriend of then-WWE Champion Seth Rollins, NXT Diva Zahra Schreiber, got released for "inappropriate and offensive remarks". Back in 2012, she posted pro-Nazi artwork onto her Twitter account and somebody dug it out. She tried to defend it by stating swastikas stood for "peace", but her explanation fell apart when one of the photos was a pony à la My Little Pony with a swastika armband and a handlebar mustache, clearly meant as a send-off to Hitler. Granted, she was probably still on thin ice after the nude photo scandal earlier that year when somebody posted a nude photo of her to his social media accounts (the contents of which are automatically published by WWE.com) and then Rollins' then-fiancee Leighla Schultz posted a nude photo of him to her twitter account. This was just it for them, seeing as she doesn't have clout or leverage that Seth does and this wasn't too far off Hogan's firing for similar reasons.
TNA Knockout Jessicka Havok was having a tryout match for in 2015 WWE. Things were apparently going well until fans who recognized her uncovered tweets she had made in 2011 using racist and homophobic slursnote Havok was part of the Midwest Militia, whose biggest feuds then were with the black Soul Sisters, Dominican Marti Belle and Puerto Rican Mercedes Martinez in WSU, a promotion also known for its Butt-Monkey "boy diva". These facts were not enough to explain or excuse everything she tweeted, however, and Havok deleted most of them in the realization she had gone overboard. But once something is on the internet, it is really hard to get off the internet. In this case the tweets came back to haunt her four years later - and started broadcasting them online. She ultimately wasn't hired.
Masada of the Carnage Crew was offered a deal with TNA in April of 2016 which ended up not working out when he was arrested for stumbling around drunken in public (he slipped and hit his head), also getting company founder Jeff Jarrett in trouble by association (he was in the process of finalizing the deal with him) and Teddy Hart arrested (for having paid for Masada's alcohol, roughly 700 USD spent).
Titus O'Neil almost faced this as he was almost fired after he had playfully grabbed Vince during the Daniel Bryan's retirement episode. Instead he was suspended for 60 days that was originally 90.
Subverted with NXT Diva Aliyah. Old tweets using racial slurs were uncovered on her account. However WWE issued a statement that the tweets had been made by someone else using her account - not to mention being made when she was only seventeen - and she remained under contract.
Matt Sydal was busted entering Japan with marijuana stashed in his luggage in Mid 2016, Japan's strict drug laws caused NJPW to break ties with him immediately, which was a blow to them as Sydal was a third of the NEVER Openweight Six man Tag Team Champions alongside Satoshi Kojima and Ricochet, forcing them to vacate the belts. The team eventually reformed and won the titles back with Sydal's place being taken by David Finlay Jr (son of Irish 90's WCW mainstay David "Fit" Finlay). After he was charged with possession on September 29th of 2016, Sydal very publicly announced he was done with NJPW .
In 2017 AAA stripped perennial Reina De Reinas Taya Valkyrie of her title belt for not showing up to defend it on a show she hadn't been scheduled to appear on.note The Kayfabe reasoning for this was that she'd used a weapon during her last defense, except it was a no disqualification match. This lead to her real life and on screen fiancee Johnny Mundo storming out in protest after being tricked into handing them her belt "for a photoshoot". Although AAA continued to keep putting him on shows, Valkyrie had no such luck, and she doesn't seem interested in going back after the way she was treated either.
Sexy Star found herself blacklisted from several wrestling promotions in 2017 after an incident where she applied a legitimate armbar submission to Rosemary at the end of a match - with the apparent intention of hurting her. At the time she held AAA's Reina De Reinas title belt and was immediately stripped of it. A statement where she refused to apologise and was accused of Victim Blaming didn't help matters either.
Jimmy Jacobs was fired in October 2017 from his job with the WWE Creative Team after he put a selfie of himself posing with members of Bullet Club from a Ring of Honor event on his Instagram page. Supposedly the justification was that doing so was promoting a rival company.
Enzo Amore was released from WWE and stripped of the Cruiserweight title in January 2018 after sexual assault allegations were made against him, although the firing was due to being under investigation since October and not telling the company about it until the accused victim broke her silence hours before Raw's 25th Anniversary.
Michael Elgin lost his booking job for Glory Pro Wrestling and many of his North American bookings after he was found to cover up a sexual assault allegation against a student of his, as well as pursuing an affair with the victim and badmouthing fellow wrestler Jeff 'Mantanza' Cobb. Averted in New Japan, as he did manage to keep his job there.
