UFC 213 has lost its scheduled main event on the day of the show.
Ariel Helwani first reported on his Twitter account this afternoon that Amanda Nunes, the UFC women's bantamweight champion who was supposed to face Valentina Shevchenko in
the main event tonight, is currently in the hospital.
Helwani noted that Nunes has been feeling ill all week. The fight wasn't officially off when he first tweeted, but he then confirmed that it wouldn't be happening in a post on MMA Fighting.
The Yoel Romero vs. Robert Whittaker fight for the interim middleweight title will now be moved to the main event position and one of the prelim fights will be moved up to the main card. The rest of the pay-per-view lineup includes Fabricio Werdum vs. Alistair Overeem, Daniel Omielanczuk vs. Curtis Blaydes, and Anthony Pettis vs. Jim Miller.
Travis Browne vs. Aleksei Oleinik is the top fight scheduled for the FS1 prelims.
