​In his UFC debut, ​Greg Hardy's night went terribly wrong. The former Carolina Panthers and Dallas Cowboys star who was unceremoniously shunned from the NFL after domestic violence charges were brought against him took his talents to the octagon on Saturday night, hoping to prove to Dana White and Co. he's worth the risk. Sadly for Hardy, he did the exact opposite. ​Hardy illegally kneed his opponent when he was down, prompting what per the rules must be an immediate disqualification. We kid you not.

Hardy basically had this match won against Allen Crowder, as his opponent was leaning over seemingly begging for the match to end. But Hardy couldn't help himself, and kneed Crowder directly in the head in an absolutely dirty move, even in UFC circles.

Hardy should be ashamed, and we really shouldn't be surprised.
