UPDATE: Bernd Boente, Wladimir Klitschko's manager, told ESPN that with so little time to promote and market such a huge fight against Anthony Joshua both camps agreed to look to do the fight in the spring, as long as the WBA sanctions it for the vacant title. Boente said Klitschko has a mild muscle pull in a calf and that, combined with there being only five weeks until Dec. 10 and no decision yet from the WBA, Klitschko decided to wait until spring. So Joshua will still fight somebody else Dec. 10 and then face Klitschko in the spring if the WBA is on board.
