This is what you happens when a 48 year old ex-boxer with a MMA record of 0-1 takes on a MMA heavyweight ranked top ten in the world. According to Sherdog, Mercer knocked out Tim Slyvia in 9 seconds with a right hook. It just took one punch...just one to finish up the former UFC heavyweight champion. So what happens now? Ray Mercer goes to Dream and fights in Japan? The dude knocked out a top ten WAMMA heavyweight, that should give him some clout in the industry. Earlier this week I said if Mercer beats Tim Sylvia, it would be the greatest upset in the history of MMA and I'm still standing by it. Tonight at Adrenaline MMA III, the world witnessed the greatest upset in MMA history. On the bright side, our guy, Jeremy Horn won his 8,077,480 fight with a rear naked choke in the first round. Nicely done Horn. [Source]
