NEW YORK - Brazil’s Alex Pereira pulled off a stunning comeback to knock out Israel Adesanya in the fifth round and claim the UFC middleweight title and Zhang Weili choked out Carla Esparza to regain the strawweight belt at UFC 281 at Madison Square Garden. Behind on the judges’ scorecards and running out of steam, Pereira unleashed a stunning combination of strikes in the final round to dethrone Adesanya, who had held the title for 3-1/2 years, in only his eighth professional MMA bout.
