Joe Rogan's Incredible Reaction To Kamaru Usman Knocking Out Jorge Masvidal At UFC 261

Referee Herb Dean stepped in to call an end to the fight as the Nigerian-American UFC star successfully defended the welterweight title for the fourth time.

Rogan, who was on commentary at UFC 261, was in complete shock as fans erupted in celebration at the VyStar Veterans Memorial Arena in Jacksonville, Florida.

Usman's second victory over Masvidal extended his impressive MMA record to 19 wins and one defeat.

The UFC welterweight champ hasn't suffered defeat inside the octagon since his first-round submission loss to Jose Caceres in 2013.

Speaking after the UFC 261 fight, Usman insisted that he is "still getting better" and declared that he is the "pound-for-pound best fighter on the planet right now."

Usman explained: "I told everybody, I'm still getting better. The sky's the limit for me as long as I'm doing this.

"I know with my fundamentals, I am the pound-for-pound best fighter on the planet right now."

Masvidal, meanwhile, admitted that it 'hurt' to suffer his first knockout defeat as he said his opponent "showed me something that he didn't show in the first fight."

The 36-year-old UFC fighter said: "First time in my career, and it's in front of all my people, my family and my friends, so it hurts.

"I've never been knocked out in 50 pro fights. Usman showed me something that he didn't show in the first fight.

"I didn't feel his power, and that's what happens when you get overconfident. I thought we were going to wrestle more.

"All the props to him in the world. He caught me by surprise. He's got my number.

"There's nothing I can say. He won this fair and square. God bless him."
