Tallison Teixeira’s undefeated run is no more.

Derrick Lewis more than made sure of that.

Lewis easily handled Teixeira in a matter of seconds on Saturday night at Bridgestone Arena in Nashville in what was his first fight in more than a year. The 40-year-old, who is the UFC’s all-time knockout leader, added another TKO to his tally when he handled the 6-foot-7 Brazilian without much of an issue whatsoever.

Though it ended up being a complete blowout, Lewis looked like he was on the wrong side of things out of the gate. He took an early blow to the face, and was spotted holding his eye while stumbling around a bit. But Lewis flipped things around immediately. He rallied and drilled Teixeira to the ground with a left-handed punch to the chin. He then threw Teixeira into the fence, landed several shots to the head and forced the early technical knockout just 35 seconds in.

Naturally, that led to a massive celebration that only Lewis could pull off in the Octagon. He ripped his shorts off, waved them around and then even briefly mooned the ESPN camera.

The loss ended what was an otherwise dominant run from Teixeira. He entered the night with a perfect 8-0 record and coming off a win over Justin Tafa via a first-round knockout at UFC 312 in February. None of his fights have actually made it out of the first round, either.

Lewis now holds a 29-12 record in his career. He has 24 wins by knockout or technical knockout, 16 of which have now come in the UFC. That’s the most in promotional history. Lewis has now won three of his past four outings, too.

While Lewis is undoubtedly nearing the end of his career, he clearly still has a lot left in him. Saturday night’s upset was proof of that.
