Justin Gaethje knocked out Dustin Poirier with a head kick one minute into the second round to win the main event lightweight bout at UFC 291 on Saturday night.
The third-ranked Gaethje (26-4) celebrated his victory by climbing to the top of the Octagon fence and doing a backflip off it. His perfectly timed headshot helped him avenge a loss to Poirier in 2018 when he suffered a fourth-round technical knockout via strikes.
It was Gaethje’s 20th win by knockout or TKO and his seventh victory in his last nine fights.
Second-ranked Poirier (29-8) entered the rematch between the two former interim lightweight champions as a minus-152 favorite according to FanDuel. He matched Gaethje blow for blow in the first round before being quickly dispatched in the second. With the victory, Gaethje claimed a BMF belt - the second UFC fighter to be awarded that belt.
Beating Poirier opens the door for Gaethje to have a potential title bout against the winner of Islam Makhachev and Charles Oliveira, who are set to square off at UFC 294 in October.
Gaethje’s BMF win over Poirier headlined five main card bouts.
Alex Pereira defeated Jan Blachowicz by split decision in a light heavyweight bout billed as the co-main event for his eighth win in his last nine fights.
Pereira (8-2), ranked second as a middleweight, made his debut in the light heavyweight division at UFC 291 after losing the middleweight title belt via knockout to Israel Adesanya at UFC 287 in April. Blachowicz (29-10-1) did not make the transition in weight class a smooth one for the former champion.
Derrick Lewis earned a record 14th knockout win over Marcos Rogerio de Lima just 33 seconds into the first round of the heavyweight bout. The No.10-ranked Lewis (27-11) scored an immediate takedown with a flying knee and pummeled 15th-ranked Rogerio de Lima (21-10-1) with repeated punches to score the early finish. He celebrated snapping a three-fight slide by stripping off his shorts and dancing around the Octagon.
Bobby Green beat Tony Ferguson by submission via choke with six seconds left in the third round of the lightweight bout. Green (30-14-1) dominated the final two rounds to earn his second career submission, scoring takedowns in both rounds while raining repeated blows that left his opponent battered. He denied Ferguson (26-9) a shot at earning his first UFC victory since 2019, sending the 39-year-old fighter home with his sixth straight loss.
Kevin Holland made quick work of Michael Chisea to win the welterweight bout. Holland (25-9) beat the 12th-ranked Chisea — fighting for the first time following a two-year hiatus — by submission at 2:39 in the first round. He used his length and striking abilities to trap Chisea (18-7) in a D’arce choke, forcing a quick tap out.
