American journalist Dan Rafael reports that Bivol has signed his contract for his side of the deal to face Beterbiev next.

However, Beterbiev must first beat his WBC mandatory challenger Callum Smith on January 13.

If Beterbiev does emerge victorious though, he can then negotiate his side of the deal to face Bivol and potentially sign to finalise the fight in 2024.
