Fury, Usyk sign contracts for undisputed heavyweight title fight

The megafight between heavyweights Tyson Fury and Oleksandr Usyk is back on.

Fury and Usyk signed contracts for an undisputed heavyweight title fight in Saudi Arabia.

The bout could take place Dec. 23 or sometime in January, sources told ESPN's Mike Coppinger.

The two appeared to have an agreement for a fight in April, but things fell apart due to a dispute involving the revenue split for a potential rematch.

Fury (33-0-1, 24 KOs) is scheduled to take on former UFC heavyweight champion Francis Ngannou in a boxing match in Saudi Arabia on Oct. 28.

"The Gypsy King" retained his WBC heavyweight belt with a 10th-round TKO of Derek Chisora last December.

Usyk (21-0, 14 KOs) retained his WBA, IBF, WBO, IBO, and The Ring heavyweight titles with a ninth-round knockout of Daniel Dubois in August.
