Jack Catterall suffered an injury and his Aug. 24 fight vs. Regis Prograis in Manchester, England, has been postponed, sources told ESPN on Tuesday.
The junior welterweight fight will be rescheduled for a date in October, sources said.
The bout will be Catterall's second consecutive against a former 140-pound champion. In May, England's Catterall (29-1, 13 KOs) exacted revenge with a unanimous decision win over Josh Taylor in a rematch.
The performance was a career best for Catterall, 31, who is pursuing his first world title. In his lone title shot, Catterall suffered a controversial split decision loss to Taylor in February 2022.
"I've waited around for big fights to happen before, sitting around waiting for title shots, and it caused me a huge amount of inactivity," Catterall, ESPN's No. 3 junior welterweight, said when the fight was announced. "I'll never do that again. ... I'm looking forward to sharing the ring with such a great fighter."
Prograis (29-2, 24 KOs), a native of New Orleans, lost for the first time in October 2019, a majority decision setback against Taylor in London.
His second defeat came in December, a shutout decision to Devin Haney in a title defense. Now, the 35-year-old Prograis will look to rebound in a high-stakes fight.
"This is a fight I've always wanted," said Prograis, ESPN's No. 8 junior welterweight. "We were supposed to fight a few years ago but it never materialized. Now is the perfect time.
"I view Jack as one of the best in the world at 140 pounds. It's a great fight because Jack is eager to become a world champion and I'm looking to become a three-time world champion."
