Two middleweight prospects entered Bellator 283 undefeated, but Dalton Rosta was the only one who left the cage with an unblemished record. Against a rival and fellow rising middleweight, Rosta (7-0 MMA, 7-0 BMMA) handed blue chip wrestling prospect Romero Cotton (6-1 MMA, 6-1 BMMA) his first career loss at 0:38 of Round 4. The bout served as the event’s featured prelim. Bellator 283 took place Friday at Emerald Queen Casino in Tacoma, Wash. There was a little heat between Rosta and Cotton in the lead-up to the bout
