Last week, promoter Eddie Hearn discussed his desire to make a year-end full division unification between heavyweight champions Anthony Joshua and Tyson Fury.

After Fury stopped Deontay Wilder to capture the WBC world title in February, there was a road being outlined to see Joshua face Fury by year's end.

But the ongoing coronavirus pandemic may have killed that plan, at least for 2020.

Originally, Joshua was going to defend his IBF, IBO, WBA, WBO world titles against mandatory challenger Kubrat Pulev on June 20th in London, and Fury was going to face Wilder in a trilogy fight on July 18.

Both of those events were postponed due to the pandemic. Joshua is now going to face Pulev on a tentative date of July 25, while Fury-Wilder 3 has been pushed back to October.

The scenario that Hearn would like to see happen, is both Joshua and Fury sidestep their upcoming defenses and instead fight each other at the end of the year.

But that would be tricky to complete, because Wilder would have to agree to a step-aside deal - which wouldn't come cheap. And Pulev would also require a step-aside agreement, and that wouldn't come cheap either.

Anything is possible in boxing, but the scenario of both Wilder and Pulev taking step-aside deals is highly unlikely.

"I suppose anything is possible," Arum said to BBC Sport. "But Pulev has rights. He has entered into a contract. Wilder has a contract to fight Fury yet again.

"No promoter like me, Eddie Hearn or Frank Warren is going to violate a contract. So let's take a step back here, we have to respect everybody's rights. Is it possible that Pulev and Wilder step aside to let Fury and Joshua fight? Anything is possible but it's up to them."
