Mayer will defend her WBO welterweight world title in a rematch against Ryan this Saturday, March 29, at BleauLive Theater at Fontainebleau Las Vegas. Mayer (20-2, 5 KOs) edged Ryan (7-2-1, 3 KOs) via split decision following a chaotic pre-fight buildup last September, sparking calls for an immediate rematch.

In the co-feature, Brian Norman Jr. (26-0, 20 KOs) will make the inaugural defense of his WBO welterweight world championship against Puerto Rican challenger Derrieck Cuevas (27-1-1, 19 KOs).

Mayer-Ryan II and Norman-Cuevas will be broadcast LIVE on ESPN, ESPN Deportes, and ESPN+ at 10 p.m. ET/7 p.m. PT.
