Gegard Mousasi hasn’t even stepped in the cage for his first Bellator fight, but already he appears much happier with the status of his career than any point in his four-year UFC run. Mousasi (42-6-2 MMA, 0-0 BMMA) became one of several notable names to sign with Bellator through free agency this year when he inked a multi-fight deal in July. He makes his promotional debut on Oct. 20 when he meets Alexander Shlemenko (56-9 MMA, 12-3 BMMA) in Bellator 185’s middleweight headliner, which takes place at Mohegan Sun Arena in Uncasville, Conn., and airs on Spike following prelims on MMAjunkie.
