What's next for UFC 258 winners?

Another UFC event is in the books.

Kamaru Usman retained his welterweight title for the third time, a women's flyweight rose to contention, and a middleweight contender bounced back.

Here's what should come next for UFC 258's notable winners.

Kamaru Usman

Defeated: Gilbert Burns via third-round TKO
Should fight: Colby Covington or Leon Edwards

There isn't a clear-cut No. 1 contender in the welterweight division after Burns got his shot, so we will likely have to turn to a rematch for Usman's next title defense.

The champion called out Jorge Masvidal - whom he beat in lopsided fashion last summer - following Saturday's main event. The only argument in favor of Masvidal getting another title shot is that he took the first fight on six days' notice. Still, "Gamebred" hasn't stepped into the Octagon since then. Masvidal should at least have to secure one win before earning a rematch, especially considering how their first fight played out.

Rematches against Covington and Edwards make more sense. Usman defended his title against Covington in late 2019, and it resulted in an instant classic. "The Nigerian Nightmare" beat Edwards in 2015, long before either were top contenders. Covington has only won one fight since his title shot, and Edwards has been out of action since 2019, so ideally the two would face each other to determine who gets the next crack at the title.

Stephen Thompson, who's ranked No. 5 and has won two in a row, is a wild-card opponent for Usman. That matchup is arguably one of the more intriguing title bouts the UFC could make at 170 pounds, as Thompson's striking style would present Usman with a unique challenge. But it feels like "Wonderboy" still needs one more win to solidify himself as a title challenger.

Alexa Grasso

Defeated: Maycee Barber via unanimous decision
Should fight: Cynthia Calvillo

Grasso took another step toward the top of the women's flyweight division, taking out the No. 10-ranked Barber.

In a relatively shallow division, the former Invicta FC standout might only be a couple wins away from a title shot against dominant champion Valentina Shevchenko. But before that can happen, she will have to test herself against a top-five fighter to see if she's fit for title contention.

Calvillo sits at No. 5 and would be the ideal opponent for Grasso because she's coming off a loss to former title challenger Katlyn Chookagian. The promotion is likely looking to pair up Calvillo with someone around Grasso's standing since she needs to work her way back up to another top-three opponent by fighting someone ranked a little lower in the division.

This fight would determine whether Calvillo is still a top-five contender or if Grasso has what it takes to steal that ranking from her and move closer to UFC gold.

Kelvin Gastelum

Defeated: Ian Heinisch via unanimous decision
Should fight: Jared Cannonier

Gastelum is ready to get back to fighting the middleweight division's top contenders after snapping his three-fight skid against Heinisch.

The No. 9-ranked fighter should face No. 3 Cannonier in a matchup that would move one of them back into title contention. Cannonier is coming off a loss to former champion Robert Whittaker last October, but he won three in a row before that.

This fight would be pivotal in the division, and it would be a lot of fun stylistically. Gastelum is arguably the quicker striker, but Cannonier would have a significant edge in power.

Alternatively, if Gastelum wants to fight someone in the Nos. 7-10 range, he could take on the winner of Derek Brunson versus Kevin Holland. That bout is scheduled to headline a UFC Fight Night card in March.
