Payton Talbott vs. Cameron Saaiman (bantamweight)

Amanda Ribas (12-4)

Amanda Ribas dispatched Luana Pinheiro via third-round technical knockout last November to rebound from her TKO defeat against Maycee Barber. The Brazilian will look to put together a win streak for the first time since 2020. She has alternated wins and losses in her last six outings and is set to headline her UFC main event on Saturday.

Rose Namajunas (11-6)

Rose Namajunas’ flyweight debut didn’t go to plan as she suffered a unanimous decision loss against divisional standout Manon Fiorot in September.

Prior to moving up to flyweight, 'Thug' competed in three title bouts which included two consecutive victories over current divisional champion Zhang Weili. The Wisconsin native dropped the strawweight gold to longtime foe Carla Esparza in a lackluster battle in 2022 before moving up a division last year.

Justin Tafa (7-3-1NC)

Justin Tafa scored three first-round stoppage victories in his last four outings. In his latest trip to the octagon in September, 'Bad Man' knocked out Austen Lane after their first meeting resulted in a no-contest due to an accidental eye poke.

Karl Williams (9-1)

Karl Williams is riding a six-fight win streak into this bout with his last two victories coming under the UFC banner. In his latest trip to the octagon last May, the ATT standout picked up a unanimous decision win over Chase Sherman.

Edmen Shahbazyan (12-4)

Edmen Shahbazyan's UFC career has been on a downward trajectory. 'The Golden Boy' has gone 1-4 in his last five fights with three of those defeats ending in a TKO. The Californian was most recently dispatched by Anthony Hernandez last May.

A.J. Dobson (7-2-1NC)

A.J. Dobson made a 0-2 start to his promotional career but bounced back by outpointing Tafon Nchukwi last August. The Ohio native will hope to begin a winning streak when he faces Shahbazyan on the UFC card tonight.

Payton Talbott (7-0)

Payton Talbott will look to extend his record to a perfect 8-0 in his sophomore UFC appearance on Saturday. The Nevada native earned his promotional contract by outpointing Reyes Cortez Jr. at Dana White's Contender Series 2023: Week 1 and followed that up with a submission victory over Nick Aguirre in his octagon debut in November.

Cameron Saaiman (9-1)

Cameron Saaiman ended up on the wrong side of a unanimous decision against Christian Rodriguez last time out in October. The loss marked the first defeat of his professional career.

Billy Quarantillo (18-5)

Billy Quarantillo has alternated wins and losses across his last six fights. In his latest outing in August, the Florida native edged out a unanimous decision win over Damon Jackson.

Youssef Zalal (13-5-1D)

Youssef Zalal was released by the UFC after going 0-3-1 in his last four fights under the promotional banner. 'The Moroccan Devil' went on to score three consecutive first-round finishes under Sparta Combat League and is gearing up for his second stint with the UFC.

Fernando Padilla (15-5)

Fernando Padilla made an emphatic UFC debut last April, dispatching Julian Erosa via TKO in the first round. However, the Mexican ended up on the wrong side of a unanimous decision against Kyle Nelson in his subsequent outing in September. Padilla will hope to get back into the win column when he faces a streaking opponent on the UFC card tonight.

Luis Pajuelo (8-1)

Luis Pajuelo is riding a five-fight win streak into his UFC debut this weekend. Four of those wins came via stoppage with his latest triumph coming over Robbie Ring via first-round at DWCS in August.
