Chris Weidman has been ruled out of a clash with Vitor Belfort at UFC 184 after suffering an injury during training, leaving Ronda Rousey to fill the void.
It was revealed by MMAJunkie.com that Weidman had sustained an unspecified injury but it was enough for him to pull of out next month's main event.
Instead, Ronda Rousey and Cat Zingano will now headline the card in a fight for the UFC Women's Bantamweight title.
Could an interim title come into play?
This is the third time, and second in a row, that the UFC has had to cancel a fight between Weidman and Belfort and fans are growing frustrated. Their initial clash at UFC 173 was scrapped after Belfort failed a drugs test and now Weidman has had to pull out of fights at UFC 181 and 184.
It's unclear how long Weidman could be out for and although he did fight in July of last year, the UFC may opt to have bring in an Interim Middleweight title in the meantime, like they've done in the Heavyweight division.
Belfort would likely feature in such a fight and one possible opponent would be Anderson Silva, provided the Brazilian overcomes Nick Diaz at UFC 183. That would be sure fire sell-out on a Brazilian card and although Silva has expressed a mixed interest in pursuing titles, he's still ranked as the number one contender in the UFC's rankings.
Rousey-Zingano stepping up
The new main event of the evening is perhaps going to be the biggest test of Rousey's career in Zingano. Rousey has steam-rolled over the division in the past couple of years and beaten every top five fighter, except Zingano.
Their initial clash at UFC 168 was postponed due to Zingano suffering an injury and then she had to take time off to deal with her husband's death. She came back at UFC 178 and finished Amanda Nunes to reclaim the number one contender's spot that she had earned by beating Miesha Tate in April 2013.
The fight promises to be a firecracker, with both fighters having vicious finishing potential and they can also go the distance, so it makes for a great replacement for Weidman-Belfort.
