The president of the World Boxing Organisation, Francisco Varcarcel, has forced Anthony Joshua to defend his WBO title after winning Andy Ruiz on Saturday’s rematch.

The president Joshua will have to defend his title against challenger Oleksandr Usyk within 180 days of Saturday’s win.

According to Mail Online Sport, the match must take place before June 4th and if Joshua refuses to fight the Ukrainian former cruiserweight king before then, he will be forced to give up his belt.

The publication also added if Joshua gives up his belt, Usyk could face either Dereck Chisora or Joseph Parker for it which also means the belt will also be divided further.

The belt currently contains IBF, WBA and WBO titles which Joshua reclaimed on Saturday in Saudi Arabia after beating Andy Ruiz who previously held the titles back in June after defeating Joshua in New York.
