The WBA have now ordered unified heavyweight champion Oleksandr Usyk to defend against mandatory challenger Daniel Dubois next.
The news comes after the IBF ordered the Ukrainian to defend against Filip Hrgovic last month.
Usyk was ringside to witness Tyson Fury‘s ten-round domination of Dereck Chisora at the Tottenham Hotspur Stadium on December 3rd.
Fury and Usyk came head-to-head post-fight as the pair prepare to clash for the undisputed crown in 2023.
The latest moves by the IBF and WBA now cast doubt over whether all four doubts will be on the line.
Dubois recovered from three first-round knockdowns to halt Kevin Lerena in the third-round in the chief support.
