Video: Callan Potter scored a big ol' head-kick KO last weekend

The MMA world featured a full weekend of fights this past weekend, but one of the biggest knockouts may have flown under the radar down in Australia.

At Hex Fight Series 5 in Melbourne, Callan Potter (11-5) connected with a flush head kick on fellow welterweight Sam Hayward (4-1).

Early in third round, Hayward unloaded punches against the cage and then ducked his head, but Potter’s right leg connected cleanly. Hayward was knocked out cold, and the ref immediately intervened to wave off the fight.

The official stoppage came at the 0:16 mark of the final frame.

With former UFC fighter Brian Ebersole on the call, check out the fight-ending blow above.
