After more than four years, the UFC returns to Austin on Saturday with UFC Fight Night 57 at the Frank Erwin Center.

The FOX Sports 1-televised event features a 12-bout lineup that’s headlined by a hugely important featherweight matchup between top contenders Frankie Edgar (17-4-1 MMA, 11-4-1 UFC) and Cub Swanson (21-5 MMA, 6-1 UFC).

Edgar was most recently seen in the octagon over the summer, when he defeated B.J. Penn for the third time and sent him into retirement. The former lightweight champion is still fairly new to the division, but he believes a win puts him in solid position for a title shot.

Swanson, on the other hand, is riding a six-fight UFC winning streak and is on the cusp of a title shot of his own. He’s already defeated some of the division’s top contenders, but a win over a former titleholder in Edgar would significantly strengthen his resume.

The main event isn’t all the card has to offer, though. The card features several relevant matchups between ranked fighters. To dig into the numbers behind them all, here are 65 pre-fight facts about UFC Fight Night 57.
