 And Britain's Anthony Joshua has triggered his clause for a rematch against heavyweight rival Oleksandar Ossik, and the fights take place in March, and that's according to Joshua's promoter Eddie Hearn. And Joshua lost his WBAWBU IBF and IBU belts to Ukraine Ossik on a unanimous point decision at London's Tottenham Hotspur Stadium last month, a possible world heavyweight unification fight between Joshua and compatriot Tyson Furry. The WC champion was thrown into uncertainty after Furry's promoter Frank Weren said he could not see it happening.
