After what is now being dubbed as 'The Bavarian Brawl' following Dereck Chisora's points defeat to WBC heavyweight champion Vitali Klitschko, we look at six of the worst instances of high-profile fights spilling out of the ring.
Dereck Chisora and David Haye, 2012
Despite the spotlight initially being on the Klitschko/Chisora title fight, Saturday's woeful scenes in fact occurred between Chisora and British heavyweight rival David Haye, who believed he was on the verge of ending his hiatus from the squared circle to meet Vitali in a high-profile title showdown.
And after Klitschko sealed a unanimous decision over the controversial Chisora, Haye, who had been providing live commentary for BoxNation, took it upon himself to attend the post-card press conference in the upper echelons of the Olympiahalle in Munich, where his heckling led to a pull-apart with 'Del Boy.'

Larry Holmes and Trevor Berbick, 1991
Chisora-Haye was far from the first instance of a scuffle breaking out between two boxers who weren't even scheduled to face each other that evening, as evidenced over 20 years ago when Trevor Berbick decided to attend long-time rival Larry Holmes's comeback from a three-and-a-half-year break
And after Holmes stopped Tim 'Doc' Anderson after two minutes and three seconds at Miami's Diplomat Hotel on April 7, 1991, the 'Easton Assassin' remarked in the post-fight press conference that he would not consider competing against Berbick in a rematch of their fight — which Holmes had won a decade prior.
"I do not like him or respect him," said Holmes with Berbick right there in attendance, and before long the two were trading blows outside the venue. But even after the two were pulled apart, the brawl didn't end there - thanks to a drop-kick off the roof of a car.
Mark Kaylor and Errol Christie, 1985
From Florida hotels to London casinos: over a quarter of a century before Chisora and Haye were accused by the nation's fight game experts of irreparably damaging the sport's reputation, British boxing was already turning ugly.
A British title eliminator at Wembley between East London pugilist Mark Kaylor and Coventry bad boy Errol Christie was heated up by the press conference at the Stakis Regency Casino the previous month in which Christie claimed Kaylor had whispered racial abuse into his ear as the two posed for face-to-face photographs.
A fight broke out, which much like with Holmes and Berbick, could only be broken up temporarily. The two went at it again in the car park, but it was Kaylor who came out on top when it mattered with an eighth-round knockout victory that Bonfire Night at an event littered by Metropolitan Police fearing a National Front presence.
In time Kaylor would apologise for his behaviour, telling Boxing Monthly in 2009: "Back then, I had a quick temper that I'd rather not have had. There was always this spark in my head! Today, I'm embarrassed by it. Errol was a nice guy. There's no way I could behave like that now."

Michael Bentt and Herbie Hide, 1994
London was again the setting when Michael Bentt and Herbie Hide prepared to do battle for Bentt's newly-acquired WBO heavyweight title. Their photo op at the conference took a turn for the worse when Hide decided to disrupt Dulwich-born Bentt's homecoming as champion, with the contest scheduled for Millwall Football Club's old Den stadium.
Bentt said of the incident: "As part of the media campaign I was given a hat embroidered with the Millwall soccer team logo… after a few snaps of the cameras, the hat suddenly flies off my head and on to the ground. 'Hmm, that's some strange s***,' I'm thinking. The wind didn't appear to be that strong, then again we are high up above the city and a gust could've carried it off.
"It wasn't until I heard a gasp and then a snicker that I realise what happened. As I turned around to face Herbie, he had a look on his face that clearly queried 'whatcha gonna do about it?'
"In between my non-linear ping-pong, I smacked the s*** out of him. Not once, but twice. The interesting and surreal thing was that after I smacked him, he just kind of stood there in bewilderment."
The fight, held on March 13 of that year, was the end of Bentt's title reign in his first defence and sadly, that of his in-ring career as well after sustaining brain injuries which may well have killed him had he set foot in the ring again.
Riddick Bowe and Larry Donald, 1994
Riddick Bowe decided to make an early start of his attempt to bounce back from a Caesars Palace defeat to famous in-ring nemesis Evander Holyfield with an attack on opponent Larry Donald at the press conference ahead of their fight at the same arena:
Bowe stuttered his way to a points victory over Donald, who refused to share the same room with 'Big Daddy' at subsequent news conferences including one in Los Angeles, California.
"It's very hard to be in the room with a former world heavyweight champion when he pulls a stunt like that," Donald said.
Lennox Lewis and Mike Tyson, 2002
When Britain's Lennox Lewis and another magnet for mayhem in the boxing world, 'Baddest Man on the Planet' Mike Tyson, met for their pre-fight press conference, chaos was in the air.
With organisers perhaps sensing the probability of trouble, the two were set to face the media on separate podiums a safe distance apart on stage at New York City's Hudson Theatre on January 22, 2002.
You can tell by his body language that Tyson was eager to mix it up before the then-IBF, IBO and WBC heavyweight champion Lewis had even made his entrance.
The resulting fracas was named Event of the Year in 2002 by The Ring magazine and preceded Lewis's eighth-round stoppage of Tyson at the Pyramid Arena in Memphis, Tennessee on June 8.
