Scott Quigg's WBA world super bantamweight title clash with Yoandris Salinas has been rescheduled for The O2 on Saturday October 5, live on Sky Sports.
British Olympic gold medallists Anthony Joshua MBE and Luke Campbell MBE will also be in action on a star-studded bill.
Quigg and Salinas were due to meet as the chief support to David Haye's heavyweight showdown with Tyson Fury in Manchester next Saturday (September 28), but after Haye pulled out with a cut, promoter Eddie Hearn and Golden Boy quickly acted to move Quigg's bout to The O2 in London.
"It's been a busy day but you have to think on your feet in this game," said Hearn. "We looked at all the options and all roads lead to The O2 where we believe Scott Quigg will be crowned world champ.
"Luke Campbell will also join the action, with two 2012 gold medallists in action plus Kevin Mitchell, Lee Selby and some mouth-watering domestic match-ups."
Quigg and Salinas join a star-studded line-up as Joshua makes his professional bow, with British lightweight world title contender Kevin Mitchell facing Marco Lopez for the vacant IBF Inter-Continental lightweight title and unbeaten Welsh featherweight star Lee Selby set to defend his British and Commonwealth titles against Ryan Walsh.
Also on the bill, unbeaten Prizefighter champions Larry Ekundayo and Glenn Foot meet in a light welterweight battle, and another Prizefighter champion Wadi Camacho faces Tony Conquest.
