Riddick Bowe, the former World Organisation heavyweight champion, has offered Mike Tyson a $100,000 (pounds 66,000) wager to knock out Bruce Seldon in less time than he did.
Bowe has issued the challenge in a formal letter to Tyson before the World Council title holder's fight with Seldon in Las Vegas on 13 July.
Seldon lasted only 1min 48sec of the first round when he fought Bowe and that is the time to beat if Tyson agrees the bet.
In the letter, Bowe writes: "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.Reuse content
