Do not underestimate the "Slam King." Former UFC fighter Gerald Harris and 11 year MMA veteran end his career with an incredible victory at the Xtreme Fight Night event in Oklahoma on the weekend. He won the 30th fight of his career slamming his opponent Matt McKeon and left him with a broken arm in gruesome fashion. During the final fight of Harris, Matt McKeon began taunting him, where is a 'slam king'? Slam me; it did not go down well with Matt. He should have held his tongue. https:\/\/twitter.com\/GHurricane\/status\/921967446055116800 Check out the graphic video: That's not the first time; Harris finished his opponent, in the same manner, sent them crashing to the canvas. Harris also defeated David Branch at UFC 116 and Aaron Cobb at Legacy FC 63 last December with a slam.
