The women’s bantamweight matchup between Sara McMann and Amanda Nunes has been promoted from the prelims to the main card at tomorrow night’s UFC Fight Night 73 event.

The bout between Chris Camozzi and Tom Watson was moved from the main card for the event, which takes place at Bridgestone Arena in Nashville, to the prelims. The main card airs on FOX Sports 1 following prelims on FOX Sports 2 and UFC Fight Pass. A light heavyweight bout between Ovince Saint Preux and Glover Teixeira serves as the card’s main event.

The bout between McMann (8-2 MMA, 2-2 UFC) and Nunes (10-4 MMA, 3-1 UFC) is significant for the 135 pound division. McMann is ranked No. 4 and Nunes No. 7 in a division that is constantly in need of new title challengers for champion Ronda Rousey. McMann already lost one shot at Rousey’s belt while Nunes missed out on an opportunity to fight the queen of MMA when she lost to Cat Zingano. The winner of this fight could well be on their way to fighting the winner of the third fight between Rousey and Miesha Tate.

With the change, the lineup now includes:

MAIN CARD (FOX Sports 1, 10 p.m. ET)

Ovince Saint Preux vs. Glover Teixeira Beneil Dariush vs. Michael Johnson Sam Alvey vs. Derek Brunson Timothy Johnson vs. Jared Rosholt Sara McMann vs. Amanda Nunes Ray Borg vs. Geane Herrera
