UFC officials are currently seeking an opponent for women’s bantamweight Lauren Murphy (8-2 MMA, 0-2 UFC), as injury has forced Sarah Moras (4-2 MMA, 1-1 UFC) to withdraw from a planned meeting at UFC Fight Night 83.

MMAjunkie today learned of the opening on the card from a person with knowledge of the situation who spoke on the condition of anonymity because they are not authorized to publicly discuss such matters.

UFC Fight Night 83 takes place Feb. 21 at Pittsburgh’s CONSOL Energy Center. The evening’s main card airs on FOX Sports 1 following prelims on FOX Sports 1 and UFC Fight Pass.

Due to the short notice, the promotion is expected to seek a U.S.-based replacement.

The exact nature of Moras’ injury wasn’t immediately known, nor was a timetable for her return. “Cheesecake” was hoping to rebound from a July 2015 loss to Jessica Andrade.

Meanwhile, Murphy finds herself in a bit of a must-win situation, as she came to the UFC with a perfect career mark but has since suffered back-to-back decision losses to Liz Carmouche and Sara McMann.
