David Haye and Tony Bellew were both in the wrong during yesterday's press conference.
The pair were supposed to be promoting their fight at the O2 Arena on March 4 but instead had a little scrap while posing for the head-to-head photo.
Bellew, angered by Haye getting too close to his face, pushed his opponent hard in the chest. Haye then retaliated by swinging a left hook, which narrowly missed Bellew's jaw.

In the aftermath, Bellew slammed the former cruiserweight and heavyweight champion on Instagram.
Attached to a picture of Haye trying to punch him, which you can see below, he wrote: "You coward! Throwing punches without gloves on @mrdavidhaye then saying you'll leave me in a hospital bed!"

BELLEW SLAMS HAYE
It was ultimately Haye who instigated the brawl, with Tyson Fury since slamming the 36-year-old and calling him "David Gay" on Twitter in a foul-mouthed homophobic rant.
In the below tweets, he wrote: "I see David gay talking s**** again! He talks about boxing history but has no clue what he is talking about, proper s***house, bellew 2 ko em.
"To be quite frank, heavyweight boxing is s*** ATM, so-called killers fighting bums who we don't know, & old men fighting for titles."
Fury's childish reaction is due to having previous with Haye, who he was meant to fight on two occasions but couldn't because the heavyweight boxer pulled out through injury.
Asked if he would ever fight him earlier this year, Fury said: "I've made it quite clear, after what he did to me twice I'll never give him the fight. I'll never give him a pay day so people can try and build it and do what they want to do.
"He's trying to get money from me. I'm not prepared to give it to him. Just like he wasn't prepared to give me any money, I'm not prepared to give him any money.
"He is a bum and he's going nowhere. He has had his shot and he's only a cruiserweight anyway. It's great to be in this position. It's like a freezing cold beer straight out of the fridge - that's what it feels like.
"If he was mandatory for the WBA belt, I'd chuck it in the bin, because what does it really mean anyway? Let him fight someone else for it. I'm not interested in his name, his reputation or anything. As far as I'm concerned, he's not even in my division.
"No matter who he beats or who he knocks out, I'll never fight him. I don't care if they offer me £100m. It's about principles. I trained hard for two fights with him and he retired rather than fight. Now let him make some money off his own back."
