UFC 307 was held Saturday, Oct. 5, at the Delta Center. In the co-main events, Julianna Pena defeated Raquel Pennington in a split decision, and Alex Pereira scored a fourth-round TKO of Khalil Rountree Jr. Both were title fights.

The knockout that came four minutes and 32 seconds into Round 4 was the finish 17,487 fans inside the Delta Center anticipated from arguably the league’s hottest star, marking Pereira’s fourth light heavyweight title victory — each by knockout — and proving the third consecutive year that UFC in Utah’s main event ended with a knockout.
