Arnold Barboza Jr and Kenneth Sims Jr will both move up to the welterweight division in a 12-round main event from Anaheim on Saturday, March 14, live on DAZN.
The Golden Boy-promoted card will also feature world title defenses from Gabriela Fundora and Oscar Collazo.
The 34-year-old Barboza (32-1, 11 KO) is coming off of his first loss, a clear decision in a WBO super lightweight title challenge against Teofimo Lopez in May 2025. Now moving to 147 lbs, he’ll look to quickly get back on track, and will have home field advantage in Southern California against Chicago’s Sims (22-3-1, 8 KO), a 32-year-old also coming off of a loss at 140, against Oscar Duarte last August.
Sims has fought at 147 in the past. Barboza has, too, but those fights were early in his career, before he got serious and stuck at 140.
Unified WBA and WBO minimumweight champ Collazo (13-0, 10 KO) will take on Jesus Haro (13-3, 2 KO) in a Puerto Rico vs Mexico matchup. It will be Collazo’s first fight of 2026.
It will also be a first time out this year for undisputed flyweight champion Fundora (17-0, 9 KO) will face WBA interim titlist Viviana Ruiz (10-2, 5 KO), a 43-year-old Venezuelan who lives and fights out of Australia. On paper, it is not a serious challenge for Fundora, but it does keep her active.
