Zuffa Boxing announced Wednesday that former unified junior welterweight champ Jose Ramirez will square off against Alexis Rocha in a 10-round bout that will be part of preliminary action September 12 at T-Mobile Arena in Las Vegas.

Paramount+ will stream Ramirez versus Rocha in the United States as part of a five-fight preliminary card, which will begin at 5 p.m. ET (2 p.m. PT). It will also be available via DAZN in the United Kingdom and Ireland, starting at 10 p.m. BST.

Ramirez (29-3, 18 KOs) – an Avenal, California native who once held the WBC and WBO 140-pound crowns – hasn’t fought since he lost a 12-round unanimous decision to Devin Haney (33-0, 15 KOs, 1 NC) in May 2025 as part of The Ring’s event at Times Square in New York. Rocha, a southpaw from Santa Ana, California, who is ranked No. 8 among The Ring’s 147-pound contenders for a vacant championship, most recently defeated former IBF junior lightweight champ Joseph Diaz Jr. (34-10-1, 15 KOs) by unanimous decision in a 10-round match March 14 at Honda Center in Anaheim, California.

Zuffa also announced these four fights as part of the preliminary card:

■ Pablo Rubio (15-0, 5 KOs) vs. Oswaldo Molina (9-0, 4 KOs) – 6 rounds, lightweights

■ Abel Gonzalez (8-0, 6 KOs) vs. Raul Salomon (16-4-1, 14 KOs) – 8 rounds, super middleweights

■ Vlad Panin (24-2, 16 KOs) vs. Dakota Linger (17-7-3, 13 KOs) – 6 rounds, junior middleweights

■ Sean Garcia (7-1-1, 2 KOs) vs. Abraham Morales (4-1, 2 KOs) – 6 rounds, lightweights

The four-fight main portion of the Garcia-Benn event is set to start at 8 p.m. (5 p.m. PT) in the U.S. and 1 a.m. BST in the UK.

Garcia (25-2, 20 KOs, 1 NC), of Victorville, California, will defend the WBC welterweight title for the first time against England’s Benn (25-1, 14 KOs). DraftKings lists Garcia, who won his WBC belt from Mario Barrios six months ago at T-Mobile Arena, as almost a 4-1 favorite.
