Alex Pereira will fight Sergei Pavlovich in the co-main event of UFC 335 at Las Vegas’ T-Mobile Arena on December 12.The promotion announced the fight during the UFC 332 card in Salt Lake City on Saturday, which broke the record for the most knockouts and first-round finishes in one night.Pereira hasn’t fought since he was knocked out by Gane at the UFC’s White House show in JuneGettyPereira hunting UFC historyIt will be a five-round heavyweight bout as Pereira hopes to bounce back from his knockout defeat to Ciryl Gane at UFC White House in June — his first fight in the division.But the Brazilian faces one of the division’s greats in Pavlovich, who unsuccessfully challenged Tom Aspinall for the interim UFC heavyweight title in November 2023.After defeat to MMA legend Alistair Overeem on his UFC debut, Pavlovich embarked on a six-fight first-round knockout streak before losses to Aspinall and top contender Alexander Volkov.He is currently on a three-fight winning streak, having stopped Tallison Teixeira in just 39 seconds last time out.It will be a tough test for former middleweight and light heavyweight king Pereira, who is on a mission to become the first athlete to claim UFC titles across three divisions.Pereira won middleweight gold in just his fourth UFC fight by knocking out Israel Adesanya, then later claimed the 205lbs title against Jiri Prochazka on the same card Aspinall beat Pavlovich.He has since become one of the promotion’s biggest stars and will doubtless set up another heavyweight title shot should he get past Pavlovich.Gane stopped Pereira in round two of their interim heavyweight title bout, with the winner expected to fight Aspinall next to unify the division.However, Aspinall vacated the title last month due to recovery issues from nasty eye injuries sustained in his first heavyweight title defence against Gane at UFC 321.Gane was then upgraded to full undisputed champion and makes his first defence of the belt against the outspoken Josh Hokit in the main event of UFC 334 on November 14.View Tweet: https://x.com/SPavlovich13?ref_src=twsrc%5EtfwIf Aspinall isn’t ready in time, the winner of the UFC 334 main event will likely fight whoever comes out on top between Pereira and Pavlovich next.UFC 335 main event announcedThe UFC also announced the main event for its final card of the year.It’s an all-Brazilian clash as Charles Oliveira puts his BMF title on the line against Diego Lopes in a mouthwatering lightweight clash.Oliveira comfortably beat Max Holloway by unanimous decision in his last fight at UFC 326 to be crowned the promotion’s ‘baddest motherf*****.’‘De Bronxs’ previously bounced back from a first-round UFC lightweight title knockout defeat to Ilia Topuria in June 2025 by submitting top-ranked contender Mateusz Gamrot.Lopes, meanwhile, had a successful lightweight debut last time out by knocking out Steve Garcia on the South Lawn of the White House.Oliveira became the new BMF champion at UFC 326 in March after a dominant performance against HollowayGettyLopes steps up to fight his fellow Brazilian in the main event of UFC 335 for his first appearance since a huge KO at the White HouseGettyThe 31-year-old previously failed twice to win the UFC featherweight title against Alexander Volkanovski.A middleweight contest between top-ranked contenders Joe Pyfer and Bo Nickal is the only other fight announced for UFC 335 so far.talkSPORT's UFC pound-for-pound rankingstalkSPORT.com has collectively voted on the best fighters to form a regularly updated UFC pound-for-pound (P4P) rankings system for the rest of 2026 and beyond.Our P4P list will be updated regularly based on performances in the Octagon — with wins, records, title wins and defences, calibre of opponents, methods of victory and much more all determining who makes it.UFC champions Islam Makhachev, Joshua Van and Sean Strickland feature – but big stars such as Alex Pereira and Tom Aspinall miss out.
