Ramos Jr. and Mosley Jr. Join Undercard for Fundora vs. Thurman Bout

The undercard for the October 25 pay-per-view headlined by Sebastian Fundora vs Keith Thurman has added another compelling matchup—this time with middleweight implications.

Jesus Ramos Jr (23-1, 19 KOs) will face Shane Mosley Jr (22-4, 12 KOs) for the WBC interim middleweight title, joining an already solid lineup at the MGM Grand in Las Vegas.

The main event sees Fundora defending his WBC super-welterweight crown against former welterweight champion Thurman, while O’Shaquie Foster puts his WBC super-featherweight title on the line against former unified featherweight champ Stephen Fulton in a high-stakes clash.

Also on the card is a 10-round non-title bout at 154 lbs between Mexican knockout artist Isaac Lucero and seasoned campaigner Roberto Valenzuela.

With full WBC middleweight champion Carlos Adames rumored to be in talks for a unification bout with Janibek Alimkhanuly, the Ramos vs Mosley Jr winner could step into a prime position in the title landscape. Both fighters are ranked in the WBC’s top 10—Ramos at No. 5 and Mosley at No. 6.

Ramos, known for his heavy hands, already made a statement in 2025 by stopping former unified super-welterweight champion Jeison Rosario. Mosley Jr, son of the legendary Shane Mosley Sr, earned perhaps the biggest win of his career earlier this year by outpointing former two-time middleweight champion Daniel Jacobs.

With a title on the line and a clear path to a full championship shot, this latest addition adds further intrigue to what’s shaping up to be one of PBC’s strongest cards of the year.
