Shane Carwin KO’s man with one hand tied to his body

Former UFC Heavyweight Champion may be retired from MMA, but he has clearly maintained his one punch knock out power which got him to the top of the UFC's Heavyweight division. Yesterday, Carwin competed in a one-armed boxing match against retired professional skateboarder Jason Ellis. The pair squared off before EllisMania 13 and as you can see from the below, Carwin had a sizeable advantage over his opponent;

It didn't take Carwin long to unleash the power which saw him slice through the 265lbs division en route to the UFC gold on Ellis who sensibly stayed on the mat.
