To be honest I'll believe it when I see it but anything can happen in Boxing.
Wembley stadium is already booked for April but Wilder has a mandatory with Breazeale that could be pushed back once but I can't see them letting him fight Fury in December then AJ in April.
I'd be amazed if Wilder fought 3 times in 5 months and squeezed his mandatory inbetween fighting Fury and AJ. ?
