UFC 243 has reportedly lost one of its top fights after Holly Holm was forced to withdraw from her bout against Raquel Pennington.
Per ESPN's Ariel Helwani, Holm suffered an undisclosed injury and will be unable to compete on the Oct. 5 card in Australia.
The bout with Pennington would have been a rematch of Holm's first UFC appearance in February 2015.
The Holm-Pennington fight was one of five scheduled for the UFC 243 main card.
It will be headlined by Robert Whittaker and Israel Adesanya in a middleweight championship unification match.
