It’s all part of Hearns plan to age Beterbiev out,and at this moment it seems that Bivol is happy to go along with it imo .
That will add as much to his legacy as holmes over Ali, Leonard vs Duran 3, khan over Barrera, canelo vs ggg 3 or lewis over Tyson. Pointless and it should happen now for boxing and for his legacy.
Beterbiev actively sought out the IBF WBC WBO belts whilst Bivol has sat content with his WBA belt he has held for 6 years in November which shows not just a lack of ambition but which of the two fighters is actually looking to be Undisputed Light heavyweight champion and which one is not . Further to add that in this time Bivol has had 2 mandatory defences whilst Beterbiev has made 3 mandatory defences,1 of each belt and is also to fight WBC mandatory Callum Smith next which has been delayed due to Beterbiev needing surgery.If Beterbiev was promoted by Hearn he would have already had the Undisputed fight !
Just continue to shine like a Eurasian King Be what he is blessed to be and what they are cursed never to be or could ever be
