Roy “Big Country” Nelson continues to prove that he is a knockout artist, taking out former NFL player, Matt Mitrione in the headline bout at the TUF 16: Finale. Mitrione may have looked much improved after training with the Blackzilian camp, but it was still not enough as he suffered a knockout loss in the first round.

It was a sneaky uppercut that switched from a overhand from Nelson that stung Mitrione and lead to the combo that dropped Mitrione, forcing him to turtle. From there it only took a few follow-ups before ref. Herb Dean stepped in and put a stop to it.
