The lure of boxing in Las Vegas could take Carl Froch to the United States for his next fight.
Froch, who knocked out George Groves in the eighth round in London to retain his IBF and WBA super-middleweight titles, refused to identify his preferred next opponent.
James DeGale is a possibility after he won an eliminator to challenge for the IBF belt on the undercard.
Sakio Bika, Cameroon's Australia-based WBC champion, was at the news conference after the tournament at Wembley Stadium to challenge Froch to a world title unification bout.
But Froch seemed to prefer the idea of fighting in the world's boxing capital rather than settling another domestic dispute with DeGale.
"I'm going to have the summer off before I even discuss what I do with boxing," Froch told reporters. "That was one of the best nights of my career. Whatever I do now in boxing I will be a happy man. But that's not saying I'm going to retire.
"This evening will be hard to top, with it being the biggest fight in Britain since the second world war.
"But there is one box that is not ticked and that is Las Vegas. I've never boxed there, never had my name up in light down the Las Vegas strip,” Froch said.
“Before I retire it might be something I want to do. DeGale fought well but I've got a voluntary defence."
