Massive underdog knocked out his opponent with a stone cold shot to the jaw

Welcome back to the Octagon, Bosse!

After getting knocked out cold in his UFC debut, Steve Bosse returned to the Octagon Saturday night in surprising fashion.

Bosse (11-2) was a massive underdog against James Te Huna (16-9), but as it is in the UFC, one punch changed things in a hurry.

After backing off his opponent momentarily, Bosse caught Te Huna with his hands down, and struck with a 2-1-2 that caught him right on the button and put him to sleep.
