Dmitry Bivol's undisputed title run lasted a mere 44 days.
Bivol, Uncrowned's No. 4 pound-for-pound boxer in the world, informed the WBC on Monday afternoon that he will be vacating its version of the light heavyweight title that he won in his brilliant rematch with Artur Beterbiev in February.
A March 5 ruling from the sanctioning body officially ordered Bivol to defend his championship against WBC interim champion David Benavidez next. With no deal reached, the WBC ordered an April 8 purse bid for Bivol vs. Benavidez, which Bivol has now withdrawn from less than 24 hours before it was scheduled to take place.
