Perhaps the window for Karolina Kowalkiewicz was not entirely shut.

A mainstay of the Ultimate Fighting Championship women’s strawweight division for seven-plus years, the former KSW titleholder will look to continue an unexpected late-career resurgence when she faces Vanessa Demopoulos in the featured UFC Fight Night 223 prelim on Saturday at the UFC Apex in Las Vegas. Kowalkiewicz enters the Octagon on the strength of back-to-back wins. She last competed at UFC 281, where she took a unanimous decision from Silvana Gomez Juarez in their three-round encounter on Nov. 12. Demopoulos, meanwhile, has rattled off three straight victories. She last appeared on Nov. 19, when she outpointed Maria Oliveira to a unanimous verdict at UFC Fight Night 215.

As Kowalkiewicz and Demopoulos march toward their forthcoming battle at 115 pounds, a look at some of the numbers that have accompanied them to this point:

37: Years of age for Kowalkiewicz, who was born in Lodz, Poland, on Oct. 15, 1985.

3: Kowalkiewicz wins by submission, accounting for 22% of her career total (14). Her methods of choice: two rear-naked chokes and one armbar. Kowalkiewicz holds one other win by knockout or technical knockout (7%) and 10 more by decision (71%).

954: Significant strikes landed by Kowalkiewicz as a UFC women’s strawweight, placing her fourth on the promotion’s all-time list at 115 pounds. Only Joanna Jedrzejczyk (1,676), Angela Hill (1,669) and Tecia Torres (976) have been credited with more.

44: Rounds completed by Kowalkiewicz as a professional mixed martial artist. She has gone the distance on 14 different occasions and carries a 10-4 record in those bouts.

124: Combined victories between the seven opponents—Jedrzejczyk, Jessica Penne, Xiaonan Yan, Alexa Grasso, Michelle Waterson-Gomez, Jessica Andrade and Claudia Gadelha—who have beaten Kowalkiewicz. They sport a cumulative .734 winning percentage at 124-45.

34: Years of age for Demopoulos, who was born on Sept. 22, 1988 in Cleveland.
