Terrance McKinney KOs Matt Frevola in 7 seconds, injures self in celebration

McKinney fought Matt Frevola on the early prelims and dropped him right away with a one-two to score a knockout.

It is now the fastest KO win in UFC lightweight history — and the fourth-fastest KO in UFC history overall.

Following the fight, McKinney jumped off the cage in celebration and appeared to hurt his knee in celebration.

But his tears, he said in his post-fight interview, weren’t ones of pain, but ones of joy to accomplish something incredible after his long journey to the UFC.
