Ray Mercer knocked out the 310-lb former UFC champion, Tim Sylvia, at the Adrenaline 3 card in Alabama this weekend. Sylvia, who has wins over Andrei Arlovski, Jeff Monson and Ricco Rodriguez, was said not to be taking this fight seriously. His own teammate, Jens Pulver, said that Sylvia was making a mistake in taking on the fight. A 12-second knockout seems to prove Pulver right.
