I would not be surprised if Fury does knock Wilder out cold within 5 rounds. If Wilder manages to throw several of those right hands but they do not connect with the Fury chin or if they have little or no impact then what effect will it have on the Wilder mindset?

In the course of the re-match several rounds in, if Wilder consider his biggest threat (his right hand swing) being null and void or totally ineffective against Fury then how will that shape his attitude to the remainder of the fight?

And yes, if his right hand/wrist/arm has not healed then he should not go in to the re-match until he is fully fit and ready but there is plenty of time for him to recover before he steps in to the ring.
