Alex Pereira will defend the undisputed Ultimate Fighting Championship light heavyweight crown when his rematch with Jiri Prochazka headlines UFC 303 this Saturday at T-Mobile Arena in Las Vegas. Meanwhile, Brian Ortega collides with divisional upstart Diego Lopes in the three-round co-main event at 145 pounds.

Pereira has emerged as one of the UFC's box-office draws with his undeniable charisma and lethal punching power. The 36-year-old Brazilian kickboxer has posted seven wins across his eight assignments inside the Octagon. Pereira last suited up at UFC 300, where he wrecked Jamahal Hill with punches a little more than three minutes into their April 13 pairing. Prochazka, meanwhile, has rattled off 14 victories in 15 appearances, a second-round technical knockout loss to Pereira at UFC 295 the only hiccup. He, too, last competed on April 13, when he buried Aleksandar Rakic with punches in the second round of their UFC 300 encounter. Prochazka has delivered 29 of his 30 career victories by knockout, technical knockout or submission.
