Congratulations to Kelvin Gastelum for winning his welterweight debut by submitting Brian Melancon via rear naked choke in round one. Coach Mike Dolce managed Gastelum’s weight cut down to 170 lbs. from his former fighting weight of 185 lbs. The newly minted welterweight stepped into the Octagon at 194 lbs. Dolce pointed out this was the same fight-night weight at which Gastelum fought for and won The Ultimate Fighter 17 title as a middleweight.
