AJ seems boxed in now, defend the belt against Usyk or vacate the belt (de value a Future Fury fight) and rematch Dillian Whyte are his only options as far as I can see.

"The WBO are set to order Anthony Joshua to defend his world heavyweight titles against Oleksandr Usyk within the next 48 hours, sources have told Express Sport.
Usyk has been in the gym for two months in Kiev training "to become a real heavyweight" and August 21 and August 28 have already emerged as potential dates for the showdown which is expected to land in London."
