MILWAUKEE – The UFC’s final card on the FOX network has gone from 13 fights to a dozen.

The women’s flyweight bout between Jessica-Rose Clark (9-5 MMA, 2-1 UFC) and Andrea Lee (9-2 MMA, 1-0 UFC) at UFC on FOX 31 was scrapped today when Clark was ruled unfit to compete by UFC doctors.

“On Friday morning UFC flyweight Jessica-Rose Clark was deemed medically unfit to compete by UFC physicians,” a UFC official said in a statement released to MMAjunkie. “As a result the scheduled flyweight bout with Clark and Andrea Lee has been cancelled.”

UFC on FOX 31 takes place Saturday at Fiserv Forum in Milwaukee. The main card airs on FOX following prelims on FS1 and UFC Fight Pass. The fight between Clark and Lee was scheduled for the FS1 prelims.

It is not yet known which fight from the UFC Fight Pass prelims will move up to the six-fight lineup on FS1.

Clark was looking to rebound from a decision loss in June to Jessica Eye at UFC Fight Night 132 in Singapore. The setback snapped a three-fight winning streak that included decision victories in her first two UFC fights against Bec Rawlings and Paige VanZant.

Lee is riding a five-fight winning streak. She came to the UFC officially earlier this year as LFA’s women’s flyweight champion. In May, she took a decision from Veronica Macedo in her promotional debut in Chile. The win was given $50,000 “Fight of the Night” honors.

The UFC on FOX 31 lineup now includes:

MAIN CARD (FOX, 8 p.m. ET)

Kevin Lee vs. Al Iaquinta Edson Barboza vs. Dan Hooker Rob Font vs. Sergio Pettis Jim Miller vs. Charles Oliveira

PRELIMINARY CARD (FS1, 5 p.m. ET)
