Charles Oliveira is finally a UFC champion.

The 31-year-old Brazilian professional mixed martial artist finished Michael Chandler via TKO at 19 seconds of the second round on Saturday night in the main event of UFC 262 at Toyota Center. With the victory, Oliveira captured the vacant UFC lightweight title.

“I told you I was going to knock him out, and I came and knocked him out,” Oliveira said in his postfight interview through an interpreter. “I proved to everybody I’m the lion of lions.”

In the opening seconds of the second round, Oliveira dropped Chandler with a left hook and then poured it on with strikes on the ground. Chandler tried his best to get away, but he could not. Oliveira landed until referee Dan Miragliotta pulled him off, ruling it a TKO.

Oliveira quickly climbed out of the cage to celebrate after the finish and came right up to UFC president Dana White.

At the postfight news conference, White said Oliveira told him, “Thank you for everything you’ve done for me. Tonight was the biggest opportunity for my life.”

“That was an incredible main event,” White said. “Both guys had an unbelievable performance in that fight. Oliveira pulled it out.”
