Former UFC champ Shane Carwin scores brutal knockout with only one hand

The Shane Carwin comeback train got rolling this weekend, though not exactly in the way many people expected.
Carwin took on professional skateboarder and entertainer Jason Ellis in an exhibition boxing match on Saturday that headlined EllisMania 13, an annual event staged by Ellis.
The catch? Carwin had to compete with one hand duct-taped to his side.
But, yeah. It didn't matter much. Catch video of the knockout below.All weighed in. This one is official. BAD NEWS for @EllisMate. #Ellisman
