In a recent interview with BBC Sport, heavyweight contender Deontay Wilder (27-0, 27KOs), who won an Olympic bronze medal, promised to cripple Audley Harrison, a 2000 Olympic gold medal winner, with a retirement knockout on April 27th in Sheffield. The battle of Olympic medal winners will take place on the Amir Khan vs. Julio Diaz undercard.

"I'm the knockout king and I've got to keep that name going," said Wilder. "So I'm predicting a knockout. If I connect correctly, I can put you into retirement - or a retirement home. He's a guy that has a lot of heart. He falls and he keeps getting back up - I like that in him, the fact that he wants something so badly that he keeps going.

"But I don't think he's going to stop Deontay Wilder from doing what he's got to do. He's on a mission but I'm on a mission, too. I'm the next heavyweight champion of the world, I don't see no man who's going to stop me."
