Holmes made the 5th defence of his WBC world heavyweight title against Italy's European champion Lorenzo Zanon at Caesars Palace in Las Vegas, Nevada and started as a 10 to 1 favourite.
After being knocked down twice in the fourth round, Zanon somehow made it to the 6th round when the champion finished the fight with a big right hand that prompted referee Ray Solis to count Zanon out at 2:39 of the round.
