Ray Mercer

Ray Mercer, a former WBO heavyweight champion who fought the likes of Larry Holmes, Evander Holyfield and Lennox Lewis during his boxing career, continued his foray into mixed martial arts Saturday night in Alabama.His opponent? Former UFC heavyweight champion Tim Sylvia, who at 33 years old looked more washed-up than the 48-year-old Mercer. This fight was originally scheduled for May in Atlantic City, but Mercer couldn't get sanctioned by New Jersey's Athletic Commission.

It was the type of fight that makes us think of the movie "Diggstown" with James Woods and Lou Gossett Jr. Just watch Sylvia collapsed on Mercer's first punch nine seconds into the fight.
Former WBO heavyweight champion Ray Mercer, 15-years older and 50-pounds lighter than his opponent Tim Sylvia, needed just 10-seconds to knockout the 310-pound former UFC heavyweight champion on Saturday in the main event of Adrenaline III in Birmingham, Alabama.

UFC veterans Rich Clementi and Jeremy Horn both picked up first-round submission victories on the Adrenaline III undercard.Adrenaline III: “Bragging Rights” finally took place tonight (June 13) at the BJCC Arena in Birmingham, Ala., featuring a main event between former UFC champion Tim Sylvia and former WBO World heavyweight professional boxing champion and Olympic gold medalist, Ray Mercer.Talk about a huge setback for Sylvia. He was expected to crush the 48-year-old Mercer, who had just one MMA bout to his credit — a submission loss to Kimbo Slice of all people. But he didn’t.
