VANCOUVER, British Columbia (AP) — Canadian lightweight Sam Stout knocked out veteran Yves Edwards on the undercard of UFC 131 on Saturday.
Stout connected with a left hook in the first round and Edwards toppled backward. Stout (15-4-1) went to follow up, but held back when he saw Edwards was motionless.
Edwards (40-17-1) eventually got up on a stool to the applause of the crowd but needed a helping hand as he was led away.
The 27-year-old Stout, who is from London, Ontario, celebrated the victory with a backflip in the cage.
Heavyweights Shane Carwin and Junior Dos Santos were scheduled to meet in the main event, with the winner getting a shot at champion Cain Velasquez.
