Carl Frampton and Scott Quigg are in a dispute over who will use the home dressing room for Saturday's unification fight at the Manchester Arena.
The super-bantamweight pair will go toe to toe this weekend with their IBF and WBA titles on the line.
During Thursday's press conference, there was some shoving between the two and it has emerged that Frampton wants Quigg's dressing room because he claims that he is headlining the event.
"It's a bit of a laughing matter on my part and there is a bit of dispute about the dressing room," The Mirror quotes Frampton as saying. "Scott wants the dressing room that the star of the show should have.
"Contractually I'm the A name, I'm coming to the ring second, it's Frampton v Quigg."
The Northern Irishman is unbeaten in 21 professional fights, while Quigg has 31 wins and two draws from 33 outings in the paid ranks.
