Josh Taylor and Jack Catterall had to be separated at ringside as the bitter rivals clashed ahead of their rematch.
Taylor and Catterall were at the Manchester Arena to watch Chris Eubank Jr take on Liam Smith later on Saturday night. They were separated by just three seats with promoter Ben Shalom taking up position between the BOXXER stablemates.
But Taylor, who was a controversial winner of the rivals' first fight last February, became annoyed by Catterall and ended their conversation by standing up and moving towards the Englishman. Security were quick to step in and both fighters eventually returned to their seats.
But reports on Saturday night claimed Taylor has hurt his foot, an injury which will see his March 4 rematch with Catterall pushed back again. The sequel, should it take place, will only be for one world title after Taylor gave up his other three in order to purse the rematch.
Catterall, who was judged the winner by almost everyone other than the judges last year, recently told Sky Sports : "For me it's more about fighting Josh and getting the win this time, and proving to the public that it wasn't the case [of Taylor having an off night] and I do belong at world level.
"[Not being an undisputed fight] changes things slightly but I've always set out to be world champion and over the last couple of years I've been closing in on that dream. It got taken away in February but fortunately we've still got the WBO title, and I believe the Ring Magazine title, on the line.

"That's motivation in itself, to become world champion. I'm obviously not looking past Josh but it'd be nice to go out and unify the division myself." Taylor, who insists he won the first fight, added: "It's no secret the performance I put on the last time was terrible," he told Sky Sports News . "It was the worst I've ever been.
"But a lot of that was down to myself, a lack of motivation, a lack of drive, a little bit of complacency was creeping in a bit as well. It's a different approach this time mentally, I'm more switched on and taking it seriously. I don't think I need to change too much tactically-wise, but definitely it'll be a different fight."
