For the third time this year, light heavyweight champion Alex Pereira puts his title on the line in the main event of a UFC pay-per-view, taking on rising contender Khalil Rountree Jr. to close UFC 307 in Salt Lake City.

In the roughly 11 months since Pereira clinched the vacant title with a round-of-16 knockout win over former champion Jiri Prochazka at Madison Square Garden last year, the 37-year-old Brazilian has made consecutive successful title defenses against the former Defending champion Jamahal Hill earns UFC 300 and a second stoppage against Prochazka at UFC 303 to increase his win streak overall to four. “Poatan” remains one of the most feared finishers in the UFC – a devastating striker with uncanny speed and technique for someone his size, and someone truly capable of changing the course of a fight with a single thud.

Order UFC 307: Pereira vs. Rountree Jr.

Rountree Jr. arrives in Salt Lake City on a five-fight win streak, having posted finishes in four of those contests, each more devastating and resounding than the last. In his last appearance, the 34-year-old challenger stopped Anthony Smith in the third round of a fight he won handily, rocking him back and forth with a sharp, powerful left hand before “Lionheart” slowly collapsed to the canvas and Rountree Jr. stood above him, the follow-up shot was fired and loaded, but never fired.

It’s a cliché to say that a fight “will be fireworks,” but this is one of those cases where that statement feels incredibly apt. Pereira has come by finish in six of his eight UFC victories, including each of his last three outings, while Rountree Jr. has finished things inside the distance in seven of his nine UFC triumphs. Both men thrive in exchanges, meaning whoever lands the heaviest punch first could turn out to leave Delta Center with the light heavyweight title in tow.
