Several of Britain's largest sporting arenas are under consideration to stage the rematch between Carl Froch and George Groves that has finally been agreed for May 31.
Eighty-two days after the bitter rivals fought a nine-round thriller that ended with Froch stopping his younger opponent in controversial circumstances, they have agreed to meet for a second time.
Matchroom promoter Eddie Hearn views it as the biggest fight in British history and name-checked several major venues as possibilities to host a showdown that Froch starts as odds-on favorite.
Old Trafford and the Emirates Stadium are the leading contenders for Groves' second shot at Froch's WBA and IBF super-middleweight showdown, and Hearn admits the bout had to happen.
"We're in discussion with six or seven stadiums all over the country right now," Hearn told Sky Sports News.
"They are huge stadiums because this is a huge event. We're looking at a crowd of up to 80,000 for this fight.
"We've had discussions with Old Trafford, Wembley, the Emirates Stadium, the City Ground, Twickenham, Cardiff... It's a special fight.
"Over the next week we'll be closing off a deal with one of those big stadiums that we need to cater for this fight.
"I believe this will be the biggest fight in British boxing history and I want to see how big we can make it because it appeals to everybody.
"It was difficult to arrange because there were two egos to deal with, but it would be a travesty if it didn't happen.
"The fact is they don't like each other and they don't do a very good job of hiding that."
