The much-anticipated third fight between Fury and Wilder was pushed back last year due to the COVID-19 pandemic.
The Brit stopped Wilder in the seventh round of his game in February 2020 to remain undefeated in 31 fights.
After months of arbitration between the two, Judge Daniel Weinstein has ruled the couple must have a rematch before September 15, the Daily Star reported.
Attempts to reach Weinstein have not been successful.
The ruling jeopardizes a long-awaited title showdown between Fury and Joshua, the world’s two biggest heavyweights, announced for August 14th in Saudi Arabia last week.
