Watch: McKee destroys Mazzotta with head kick at Bellator 178

AJ McKee wasn't kidding about being tired of going to the scorecards.

One of MMA's rising stars, the 22-year-old lightweight opened up Friday's Bellator 178 main card with a disgusting head kick that rendered Dominic Mazzotta unconscious just 1:15 into Round 1. It was McKee's first knockout in his past four fights, and he made sure it was one that everyone will be talking about for a while.

McKee is now 8-0 in his career, and has emerged as one to watch in the Bellator cage despite turning pro just two years ago under the tutelage of his father, Antonio - a 37-fight MMA veteran.
