As Canelo Alvarez and Caleb Plant exchanged blows, the expression on Jimmy Lennon Jr's face said it all.
Unperturbed, unfazed and unimpressed, this was nothing Lennon Jr had not seen before.
After all, press conference brawls and boxing go hand in hand.

Canelo and Plant are not the first fighters to throw punches before the first bell and they won't be the last, either.
No matter how far back you go, boxing press conferences have always been the same: animated, feisty and rarely ever dull.
It's an event where death threats, tables being thrown and even Batman costumes are nothing out of the ordinary.
Here, in no particular order, Sportsmail pick out some of the craziest and most infamous brawls at press conferences and face offs in recent memory.
Mike Tyson and Lennox Lewis's press conference scrap
Mike Tyson often trespassed the line of decency in his career and starting a fight with Lennox Lewis out of nothing at their pre-fight press conference was one of those times.
It was one of the first promotional events for the fight and tongues were certainly wagging afterwards. After Lewis took his place across the room from Tyson, the 'Baddest Man on the Planet' marched across to his rival, took a swing at his bodyguard and all-out carnage broke loose. In the melee, Tyson even tried to bite Lewis' leg and was subsequently ordered to pay his opponent $335,000. Tyson later exclaimed to the room he wanted to 'eat Lewis' children'.
There was so much hostility between the pair throughout the build-up that even moments before the fight, a line of security staff had to separate them whilst the referee read out his instructions. Lewis would have the last laugh, knocking out Tyson in brutal fashion in the eighth round.

Derek Chisora throws a table at Dillian Whyte
There is a fine line between hyping a fight and going against the codes of conduct of the sport. It's fair to say Derek Chisora crossed it when he threw a table at Dillian Whyte. It was no secret that these two were not the best of friends and a fiery build-up was expected.
Chisora has a knack for attracting controversy, having previously spat, bit and slapped his opponents, so it came as little surprise when his temper got the better of him after Whyte threatened to attack him in the streets if he saw him.
An enraged Chisora, who had now lost interest in making threats, stood up and launched a table in Whyte's direction. Whyte's trainer Mark Tibbs threw his microphone in retaliation as tempers boiled over before the press conference was brought to an abrupt end.

Chisora and David Haye trade punches
David Haye and Chisora were involved in an ugly clash in Munich in 2012 after the latter's defeat to Vitali Klitschko. After throwing obscenities at one another during the post-fight press conference, the two heavyweights confronted each other and things quickly got out of hand.
Haye, clutching a glass bottle, launched a punch at Chisoram instantly sparking a mass brawl. After scrapping with Chisora, Haye then attempted to hit his rival's trainer on the head with a camera tripod. Chisora claimed Haye had 'glassed' him and vowed to 'shoot' and 'burn' the former heavyweight champion after the altercation.
Off the back of their scrap, Chisora and Haye met in the ring under Luxembourg Boxing Federation licenses after the BBBoC (British Boxing Board of Control) revoked theirs. Haye violently knocked out Chisora in the fifth round to win their grudge match.
