UFC 261 results, highlights: Kamaru Usman crunches Masvidal with ruthless knockout, Weidman Off due to Injury.

Kamaru Usman — the most decorated Welterweight champion since Georges St-Pierre.

Usman made the fifth defense of his 170-pound title by knocking Jorge Masvidal out cold in Round 2 of their UFC 261 main event rematch inside VyStar Veterans Memorial Arena in Jacksonville, Florida.

Usman (19-1) was dominant throughout in terms of takedowns and top control on the ground, which Masvidal would go on to say he fully expected.

Usman caught Masvidal (35-15) flush with a clean right cross which turned his chin and left him unconscious at 1:02 of Round 2.

The triumph extended Usman's win streak to 14 fights. It also marked the first time the iron-chinned Masvidal was stopped due to strikes in his eight-year UFC run.

Kamaru Usman.

"I am the pound-for-pound best fighter on the planet right now."

"Jacksonville, Florida, you all said you wanted violence?" Usman said. "You're welcome."

"No disrespect, thank you to my man Jorge," Usman said. "You elevated me and it has been a while since I have been extremely nervous to fight. He elevated me and made me go to the workshop and I had to sharpen my tools tonight. I am still getting better. The sky is the limit for as long as I am doing this.

Jorge Masvidal...

"First time in my career, in front of all my people, my family and my friends," Masvidal said.

"It hurts since I haven't been knocked out in 54 fights. I didn't fear his power and that's what happens."
