The Dillian Whyte-Otto Wallin fight is off for October 30.

BoxingScene.com has learned that Whyte has suffered a shoulder injury while training that has forced him to withdraw from what would’ve been an intriguing heavyweight showdown a week from Saturday night. DAZN was scheduled to stream the Whyte-Wallin fight as the main event of a card from O2 Arena in London.

Whyte would’ve defended his WBC interim title against the Swedish southpaw for the right to remain the mandatory challenger for unbeaten WBC champion Tyson Fury. Wallin was scheduled to fly from New York to London on Wednesday to start getting acclimated to the time difference a week-and-a-half in advance of the Whyte fight.

The Sun, a London-based tabloid, was first to report the news Wednesday of Whyte's shoulder injury and his withdrawal from the Wallin fight.

It is not clear if Whyte’s difficult fight with Wallin will be rescheduled or if Whyte will attempt to move straight toward a more lucrative showdown with Fury, who knocked out former WBC champ Deontay Wilder in the 11th round of their third fight October 9 at T-Mobile Arena in Las Vegas. Fighting Wallin was considered a risky proposition for Whyte, however, which could lead the Jamaican-born, London-based contender to instead seek the WBC title shot that has long eluded him.

Whyte was listed as slightly more than a 2-1 favorite to beat Wallin, according to the Caesars Sportsbook.

Wallin (22-1, 14 KOs, 1 NC) was still considered a dangerous opponent for Whyte (28-2, 19 KOs), particularly with a higher-profile opportunity to challenge Fury potentially next for him. Fury told BoxingScene.com a few days before he defeated Wilder again that he expected Wallin to beat Whyte.

Whyte, 33, regained his WBC interim title from Alexander Povetkin in his last fight.

Russia’s Povetkin viciously knocked out Whyte with a left hook in the fifth round of their first fight in August 2020 at Matchroom Boxing’s headquarters in Brentwood, England. Whyte rebounded by dominating the then-40-year-old Russian veteran and stopping him in the fourth round of their immediate rematch March 27 at Europa Point Sports Complex in Gibraltar.

Wallin, 30, has lost only to Fury in what was a more competitive fight than anticipated two years ago in Las Vegas.

Wallin impressively introduced himself to the boxing public by opening a nasty gash above the heavily favored Fury’s right eye in the second round of their September 2019 bout at T-Mobile Arena. Fury (31-0-1, 22 KOs) won their bout by comfortable distances on all three scorecards (118-110, 117-111, 116-112), yet Wallin established himself as a legitimate contender in the bout before Fury stopped Wilder in the seventh round of their rematch in February 2020 at MGM Grand Garden Arena in Las Vegas.

The 30-year-old Wallin (22-1, 14 KOs) has beaten American veterans Travis Kauffman and Dominic Breazeale in his two bouts since Fury defeated him.

The New York-based contender stopped an injured Kauffman (32-4, 23 KOs, 1 NC) in the fourth round of an August 2020 bout at Mohegan Sun Arena in Uncasville, Connecticut. Six months later, he decisively out-boxed Breazeale (20-3, 18 KOs) on his way to a wide win on all three scorecards February 20 at Mohegan Sun Arena (118-110, 117-111, 116-112).

Wallin had hoped to secure a rematch with Fury by beating Whyte.
