The former UFC pay-per-view headliner and The Ultimate Fighter 1 alum has signed with Bellator MMA, it was announced Friday night at Bellator 139.
Koscheck (17-10), one of the biggest "villains" in MMA history, has lost five in a row, the latest against Erick Silva via first-round submission in March. He has not won since a split decision victory over Mike Pierce in 2012.
However, there was a time when Koscheck, 37, was one of the best welterweights in the world. He fought Georges St-Pierre for the UFC 170-pound title in 2010 and owns wins over Matt Hughes, Anthony Johnson and Diego Sanchez.
