Kearney, Neb. – Former Nebraska-Kearney wrestler Kamarudeen "Marty" Usman won the main event at the Ultimate Fighting Championship (UFC) 245 Saturday night in Las Vegas.

Now going by Kamaru Usman, the three-time All-American and 2010 Division II national champion at 174 pounds recorded a TKO of Colby Covington at 4:10 of the fifth round. With the big blow Usman retains his UFC welterweight title. 

"I heard all week, all month, since the fight got signed, everyone is like, 'Oh, Colby is in his head, Colby is this, Colby is that. He's gonna gas out, fight emotional.' I'm telling you guys right now that the reason why I'm the best in the world is because my mind is stronger than anyone in the division," Usman told ESPN's Marc Raimondi.

It was the second-latest stoppage in a title fight in UFC history and came in a very close fight up until to that. After getting off to a slow start, Usman rallied in the third and fourth rounds.

Usman was ESPN's No. 10-ranked pound-for-pound MMA fighter coming in and the No. 1 welterweight. Covington was the No. 2 welterweight. Usman won the UFC welterweight title by beating Tyron Woodley by unanimous decision at UFC 235 on March 2.
