The countdown is on for one of the most anticipated comebacks in combat sports history, but the Ronda Rousey vs. Gina Carano fight card just hit a speed bump with only one week to go.

Scheduled for May 16 on Netflix, this monumental women's superfight marks the long-awaited return of both legends to mixed martial arts. Originally, the bout was in talks with the UFC, but financial disagreements steered the action to Jake Paul's Most Valuable Promotions, which teamed up with Netflix to make it happen. It's a clash that's been years in the making, pitting two pioneers of women's MMA against each other in a showdown that's already generating massive buzz.

However, the card suffered its first shakeup on Saturday. According to MMA Junkie's Nolan King, former UFC flyweight contender Muhammad Mokaev has been pulled from his main card matchup against former ONE Championship star Adriano Moraes. The reason? Mokaev couldn't secure his U.S. visa in time to make the trip to the Intuit Dome in Los Angeles. Stepping in on short notice is undefeated South African prospect Phumi Nkuta, who will now face Moraes in a bout that promises fireworks.

While this last-minute change is a disappointment for fight fans, the main course of the evening remains intact. The headlining act between Rousey and Carano is still set to deliver the drama, alongside a heavyweight clash featuring former UFC champion Francis Ngannou taking on Philipe Lins. And for those craving a brawl, the welterweight showdown between UFC veterans Nate Diaz and Mike Perry is also locked in.

So, is it time to panic? Not quite. The undercard may have taken a hit, but the star power at the top of this Netflix card is still ready to shine. Gear up, because May 16 is shaping up to be a night you won't want to miss.
