Fighter's punch knocks sparring partner through wall (VIDEO)

Watch as an MMA instructor gives a demonstration on punching technique while the real action goes on between the two sparring partners behind him.

In the background, a big guy lands a straight left to his taller opponent and hilariously sends him backwards through a wall.  While the big dude's knockout punch might become legend at this gym, give a little assist to the crumbling, quarter-inch drywall which just said No Mas.

The taller guy is finally pulled from the rubble, shaken and dazed, but smiling nonetheless.

That's one way to add more square-footage to their half-cage.
