British World Boxing Council heavyweight champion Tyson Fury has confirmed that he has retired from boxing in keeping with a promise to his wife, but he can reverse his decision and return to the ring again for 500 million pounds ($611.20 million).

Fury defeated fellow countryman Dillian White last April to retain the WBC title, before telling fans that he would honor his promise to his wife to retire.

"I won everything because a fighter can do whatever he wants to do...but the career with boxing is over," Fury told the Daily Telegraph on Saturday.

He added, "My career with boxing and professional fighting is over. I did everything that was asked of me and beat all the competitors I faced so that I could live after that. Isn't that wonderful and beautiful?"

And Fury, 33, said in response to a question about the amount of money that could tempt him to return to the ring, "500 million pounds .. But until this is achieved I will stay away."

And last April, Paris (Fiori's wife) said that her husband could only return to the ring to fight for the unified world heavyweight title.
