At 41 years old, Shane Carwin can still pack quite a punch.
The former interim UFC heavyweight champion took part in an exhibition boxing match at Ellismania, an annual event put on by pro skateboarder Jason Ellis.
There was one slight problem, though: Carwin had a massive size advantage. Listed at 6-foot-1, 205 pounds, Ellis stepped inside the ring with a former UFC heavyweight that frequently competed inside the Octagon at a minimum of 254 pounds.
To make things relatively fair, Carwin was forced to fight with his right arm — his dominant arm — tied to his body.
That didn’t stop Carwin from landing the knockout blow, clipping Ellis with a short left hook that sent him to the canvas.

Ellis has also shared the squared circle with UFC bantamweight Urijah Faber, who — though far more versed in the art of combat — was allowed to compete with both hands as the smaller man in the bout.
Retired for more than five years now, Carwin has recently set his sights on making a return to the mixed martial arts cage. It was initially expected that he would come back to the UFC, but that doesn’t seem to be the case any longer. He was released from his contract with the UFC, allowing the heavyweight fighter to explore his options as a free agent.
Carwin has previously defeated the likes of former UFC heavyweight champion Frank Mir, and came within a few strikes of ending Brock Lesnar’s reign as heavyweight champion when they met for a title unification fight in one of the biggest events in UFC history.
