Sullivan Cauley is pushed by Bellator as one of the promotion’s most highly-touted budding prospects. At Bellator 284 , he showed a sample of perhaps why that is. Bellator 284 took place Saturday at Sanford Pentagon in Sioux Falls, S.D., and featured Cauley (4-0 MMA, 4-0 BMMA) against Tyson Jefferies (14-11 MMA, 0-1 BMMA) in a middleweight prelim. After some feeling out on the feet, Cauley clinched Jefferies against the cage.
