The two top contenders – based on the rankings, anyway – meet in Saturday’s UFC on FOX 23 headliner.

Julianna Pena (8-2 MMA, 4-0 UFC), who’s No. 2 in the USA TODAY Sports/MMAjunkie MMA women’s bantamweight rankings, meets No. 3-ranked Valentina Shevchenko (13-2 MMA, 2-1 UFC) in the FOX-televised main event at Pepsi Center in Denver. The winner will likely get a shot at champ Amanda Nunes.

Prior to the event, which also features No. 7 welterweight Donald Cerrone (32-7 MMA, 19-4 UFC) vs. Jorge Masvidal (31-11 MMA, 8-4 UFC) in the co-headliner, check out the latest rankings for each division above.
