Weight Class: Welterweight Ildemar "Marajó" Alcantara (20-6) is 3-1 in the UFC thus far, and has promised a war in the cage against Kenny Robertson (13-3), who is coming off a win over Alcantara's countryman, Thiago Perpétuo. Younger brother of Iuri, who also fights in the UFC, Alcantara made his debut in the UFC at light heavyweight, so he's dropping a fair amount of weight to make the 170lb welterweight limit. Robertson is actually on his second run in the UFC, though his first stint with the promotion was a one-and-done. After starting his career at 10-0, he has traded wins and losses since. Combined, the two fighters have 23 wins between them, but only five have gone to decision. Expect that trend to continue, with Robertson going to sleep at some point in the third round.
