Watch The UFC 224 Post-Fight Press Conference Following The Event

It is expected that the victor will next fight middleweight champion Robert Whittaker, assuming he takes care of business as a solid betting favorite over Yoel Romero at UFC 225 next month.

It aired on pay-per-view (PPV) following preliminary-card bouts on FX and UFC Fight Pass.

Pennington's gas tank can't be challenged, having averaged 13:07 of fight time per UFC bout. Having said that, Nunes is a tremendous fighter and if she can perform at the level we know she can, I expect her to retain the title at home. The co-main event will see middleweights Jacare Souza and Kelvin Gastelum do battle in a potential title eliminator. She gets the opportunity to fight for the belt here after a proposed superfight between Nunes and featherweight champion Cris "Cyborg" Justino fell through.

No fight card is complete nowadays without a wild bantamweight scrap, and this one has it in the form of Brian Kelleher vs. John Lineker. Machida is a cautious fighter and his chin has been weakening over the years. Gastelum, 26, comes off a first-round knockout of former champion Michael Bisping last November. Dias will be in attendance.

"It's extremely exciting, just the fact for where women's MMA has come to today, and that we have this opportunity and here we are, headlining a UFC event". As good as Gastelum can be, people are quick to forget that he had no answer for Chris Weidman's ground game and was submitted in the second round. Cooper comes off a second-round TKO over Angela Magana in December. Lineker's only loss in his past eight fights was to Dillashaw in a non-title bout by unanimous decision at UFC 207 at the end of 2016. All but one of the 10 writers side with the champion. Both men are competent strikers with the power to knock out anyone while it will be interesting to see Souza's phenomenal Brazilian jiu-jitsu collides with Gastelum's wrestling. For Kelleher, the matchup might be too big of a step up in caliber. Another former champion, he won for the first time since 2015 when he beat Nate Marquardt last June.

Legends will open up the main card, as Lyoto Machida fights Vitor Belfort.

This will be only the fourth time that Belfort faces a fellow Brazilian professionally; he's 1-2. Machida, 39, is coming off an impressive decision win over up-and-coming prospect Eryk Anders, giving him his first loss. Machida was suspended 18 months from 2015-17 due to a positive drug test.
