Mikaela Mayer is set for a tough warm-up ahead of potential unification clashes when she puts her WBO and IBF super featherweight titles on the line against Jenifer Han this coming Saturday.
It's no secret that Mayer is targeting undisputed status at super featherweight and she could make a statement to the rest of the division if she beats Han in style.
Fights with either the WBC champion Alycia Baumgardner or WBA ruler Hyun Mi Choi would be next for Mayer if she leaves California with her hand raised.
Here's everything you need to know about Mayer vs. Han.
The main card is set to get underway at 10 p.m. ET / 3 a.m. BST with the main event ringwalks scheduled for 11:15 p.m. ET / 4:15 a.m. BST. These timings could change due to the length of the undercard fights.
The fight will be simulcast on ESPN and ESPN+ in the U.S, while Sky Sports will broadcast the fight in the UK.
The fight takes place at the Orange County Fair and Event Center in California.
