Joshua has taken this fight in his 11th fight after being pro 12 month or so, it took Fury till his 19th fight and nearly 4 years after he turned pro to take this fight. He hasn't bottled it from no one and he has reportedly got the fight rescheduled from what I have seen, and if he was scared which is just ****ing stupid, then he wouldn't reschedule the fight would he
I suspect this is a case of "over-training", which is something I suspect Haye suffered with as well ...and no I'm not defending either of them
