FORMER WBO heavyweight champion Riddick Bowe has offered Mike Tyson a remarkable $100,000 wager to knock out Bruce Seldon in less time than he did.

Bowe issued the challenge in a formal letter to Tyson in advance of the WBC titleholder's fight with Seldon in Las Vegas on July 13th. Seldon lasted only one minute 48 seconds of the first round when he fought Bowe and that is the time to beat if Tyson agrees the bet.

In the letter, Bowe wrote: "I hope you are up to the challenge Mike, because you're calling yourself the best heavyweight in the world."

He then included a number for Tyson to ring with his decision, adding he is waiting to hear from him.

Bowe fights undefeated Andrew Golota on July 11th at Madison Square Garden in New York.
