Hailey Cowan was scheduled to face Ailin Perez this past weekend at UFC Fight Night 220, but Cowan pulled out of the encounter on the day of the weigh-ins.
Cowan has now taken to Instagram to reveal that the reason she withdrew from her bout against Perez was due to an ovarian cyst rupture.
There is no word at this time as to when Cowan expects to make her return to action.
