Scott Quigg said he was prepared to "get changed at home" rather than risk his super-bantamweight unification fight against British rival Carl Frampton being called off because of a row over dressing rooms.
The dispute resurfaced during Friday's weigh-in at the Manchester Arena.
Northern Ireland's Frampton has threatened to withdraw from Saturday's contest because he feels Quigg, born in Bury, near Manchester, has the better dressing room.
"It means nothing to me," Quigg told Sky Sports.
"They (Frampton's camp) are getting themselves wound up, they have threatened to walk away from the fight if we get the changing room but, to let all these fans down over a changing room, come on, I'm not going to do that.
"I'll get changed at home and come to the arena and get in that ring. It means nothing to me, the changing room, it's just nonsense."
The two undefeated British world champions meet with Frampton's International Boxing Federation belt and Quigg's World Boxing Association title on the line.
Frampton weighed in at 121.7 pounds, marginally heavier than Quigg at 121.5 pounds.
Belfast-born Frampton was involved in more than a minute of staring with his English opponent, which he ended by blowing Quigg a kiss.
"This is the only real rivalry I've had in my career, it's been five years brewing and brewing, and getting bigger all the time," said Frampton.
"I feel like I'm level-headed, I took a step back and smiled and let them carry on, it's all good and all part of the pantomime.
"I am better than him. I have the power to knock him out, from the first round to the last round, and I've also got the boxing brain to comprehensively beat him on points."
As for a decision on choice of dressing rooms, Frampton said: "Why not flip a coin? Simple. Or rock, paper scissors?"
