(Reuters) - Oleksandr Usyk's reign as undisputed heavyweight world champion may last only weeks if, as many expect, the International Boxing Federation (IBF) takes back its belt due to the Ukrainian's rematch clause with Tyson Fury.

The IBF's long-time mandatory challenger is unbeaten Croatian Filip Hrgovic, who is scheduled to fight Britain's Daniel Dubois on June 1 in Riyadh.
