UFC legend Dan Henderson landed one of the nastiest knockouts of all time at UFC 199

Absolutely devastating.

UFC legend Dan Henderson (32-14) looked dead to rights in the first round Saturday night at UFC 199 against Hector Lombard (34-6-1) before handing out one of the nastiest knockouts in recent memory.

Lombard had Henderson stumbling around the Octagon as he laid bombs to legend's face, nearly submitted him and ended a dominant first round on top.

The former Strikeforce champ stormed out in the second round, caught Lombard with a vicious head kick and knocked him out cold with a stiff elbow before landing two more for good measure.

In what might be Hendo's final fight ever, it could be the cherry on what has been a supremely entertaining career.
