In a shocking upset, former UFC heavyweight champion Tim Sylvia get knocked out by 48 year old boxer Ray Mercer in 9 seconds of round number 1 at Adrenaline 3 “Bragging Rights”, according to Sherdog.

The bout was originally scheduled to be a boxing match, but was switched at the last second to avoid legal issues with boxing in a cage.

Ray Mercer:

“Everything was against me …. I whooped that ass.”

Mercer goes 1-0 in MMA, his debut mixed martial arts fight, was a first round loss to Kimbo Slice in a exhibition fight back in 2007.

This fight might set back big Tim’s plans of using this fight as a spring board him into a boxing career.
