Veteran welterweight Mike Alvarado earned a knockout against Sidney De Siqueira over the weekend... and it was in convincing fashion.

The two boxers fought for four rounds at the Pinnacle Bank Arena in Lincoln, Nebraska, before Alvarado landed a flurry of punches that had his opponent up against the ropes. After Siqueira moved to his left and squared up, he was caught with vicious right that rendered him unconscious.

It was the fourth straight win for the 37-year-old Alvarado (38-4). WOAH!
