Las Vegas Sports Consultants listed a fourth round knockout for Lennox Lewis at 10-1.
Lewis closed as a $2.50 favorite at most sports books around Las Vegas. The payoff was minus $1.40 that the world heavyweight title bout would not last past the eighth round.
Should the fight have gone the distance, the odds were 2-1 for a Lewis win.
In the undercard fights, the NABA heavyweight title was won by Sergei Lyakhovich. The native of Byelorussia, now living in Phoenix, extended his record to 15-0 with a unanimous decision over Friday Ahunanya of Las Vegas.
It was the first loss in 17 bouts for Ahunanya, who was staggered several times in the one-sided affair.
In the other title bout, William Joppe won the vacant WBA middleweight crown with a majority decision over previously-unbeaten Howard Eastman of Great Britain.
Eastman came on strong in the late rounds and knocked Joppe to the mat in the 12th round just one second before the final bell.
