Unbeaten champions face a fight to keep hold of all four belts – with AJ primed to capitalise

ANTHONY JOSHUA could be in line for a world title shot while waiting out the winner of Tyson Fury versus Oleksandr Usyk.

Fury and Usyk meet in the heavyweight division’s first four-belt unification on May 18 in Saudi Arabia.

And a rematch is to follow due to a clause in their contracts – but not all the titles are expected to be on the line for the second bout.

Filip Hrgovic is the current IBF mandatory challenger and next in line for a shot at the strap.

And by the time the rematch for Fury, 35, vs Usyk, 37, comes around the IBF gold will likely be vacated to allow for Hrgovic’s shot.

Joshua, 34, is just behind Hrgovic in the rankings and promoter Eddie Hearn is eyeing that fight for the vacant title if it does indeed become free.

It would give AJ the chance to become a three-time world champ while setting up potentially another undisputed clash between Fury or Usyk.

Joshua is coming off four wins, most recently a knockout over MMA superstar Francis Ngannou, 37.

Meanwhile, Hrgovic is in talks to fight Britain’s Daniel Dubois in Saudi on June 1 with Deontay Wilder also lined up to face China’s Zhilei Zhang.
