Tony Bellew and David Haye had to be pulled apart by security at the final press conference for their rematch which takes place on Saturday night.
The two fighters posed for photos after the conference before going head-to-head for the final time, and it took just a matter of seconds before security stepped in.
Bellew (29-2-1, 19 KOs), who emerged victorious in their previous fight back in March 2017, appeared to push Haye before the Londoner shoved him back. Neither one appeared to suffer injury and both were escorted away from one another by security.

Before the coming together, Bellew said: "He looks good, his team are confident, like last time, but we will see.
"I just want to punch him. He would love nothing more than to knock every tooth out of my mouth, don't be fooled, the mask comes off on Saturday.
"We are going to go and Haye will have to do things he doesn't want to do. I will do anything to win and you will see.
"There's going to be no rematch this time, your career is over. What matters is that you end on Saturday night."
Haye (28-3, 26 KOs) disagreed and insisted it's going to be a different outcome to the first fight.
"I've kept my gameplan under wraps but it's to do as manage damage in the first six rounds as possible and keep pushing it," said Haye. "Then I'll step it up from round seven to 12.
"If he's as tough and durable and has the heart that he and his team think they have, then we've got ourselves for a cracking fight."
