Just a day before the event, LFA 51 has a new headliner.

Women’s flyweight title challenger Jaimee Nievera (7-4) has pulled out of her title bout against champion Sabina Mazo (5-0), leaving the show without a title fight. As a result, Mazo has been pulled from the card and the co-main event between bantamweights Cody Gibson (15-7) and Gustavo Erak (19-3-1).

LFA 51 takes place Friday at Selland Arena in Fresno, Calif. The main card airs on AXS TV.

After going 1-3 in the UFC, Gibson went to work outside the promotion and won Tachi Palace Fights’ bantamweight title. But he lost it in May 2017 to Adrian Diaz. This will be his first fight since that loss.

Erak has won eight straight fights, including six by stoppage. In August, he beat Diogo Silva in his home country of Brazil. This will be his first fight under the LFA banner and first fight in the U.S.

Mazo, 21, is a Colombia native who already has posted three wins under the LFA banner. The first two came by way of first-round head-kick knockouts. Most recently, Mazo claimed the promotion’s then-vacant women’s flyweight title with a decision win over Shannon Sinn.

Nievera, 33, recently was featured on Dana White’s Contenders Series, where she stepped in on short notice to face vaunted striker Antonina Shevchenko. She lost by second-round TKO. Prior to the setback, Nievera had a three-fight winning streak that included victories under the Bellator and RFA banners.

The new LFA 51 lineup includes:

Gustavo Erak vs. Cody Gibson

Nohelin Hernandez vs. Rolando Velasco

Andres Alcantar vs. Jordan Powell

Salaiman Ahmadyar vs. Joaquin Lopez

Adam Fugitt vs. Kailan Hill

Igor Pontes vs. TBA
