Wembley Stadium will stage the rematch between Carl Froch and George Groves on 31 May, with the fight likely to set a British post-War attendance record.
Froch retained his WBA and IBF super-middleweight titles with a contentious ninth-round stoppage of Groves at Manchester Arena last November.
Froch-Groves II will be the first boxing bout at Wembley Stadium since it re-opened in 2007.
Wembley holds 90,000, although a crowd of 60-70,000 is more realistic.
Nottingham’s Froch, 36, told Sky Sports: “It needs to be held at a big stadium because it is such a good fight. I want to beat him and put closure on this whole Carl Froch v George Groves saga.
The current post-War attendance record for a boxing match in Britain is held by Ricky Hatton and Juan Lazcano, who fought in front of 55,000 fans at the City of Manchester Stadium in 2008.
Wembley appeared to be out of the running because England play a pre-World Cup friendly against Peru at the venue the previous evening.
There were reports that Manchester United, Arsenal and Nottingham Forest were all in the running to host the fight at their grounds.
