Alexander made his return to the UFC at against internet superstar Kimbo Slice at a catchweight of 215 pounds. Alexander was defeated by Kimbo Slice by unanimous decision (29–28, 29–28, and 30–27) in a bout that many thought would not make it out of the first round. The fight was characterized by Alexander circling away from Kimbo while utilizing quick but not powerful leg kicks instead of directly engaging him. While the first and third rounds were largely spent at a distance, the most spectacular moment of the fight arguably came in the second round when Slice administered a suplex that rocked Alexander. Shortly following the loss, Alexander was cut from the UFC.
