If someone considers me biased, then for example Alexander Gvozdik also expressed doubts about this whole story (even if diplomatically, but as they say, everyone understands everything).
So you're using a biased source to confirm your own bias? Oleksandr Gvozdyk is Usyk's close friend for many years so of course he is going to cast doubt on Fury.
I think given the evidence presented recently we can see the injury is genuine and probably just a freak sparring accident. Had Fury just hidden away for weeks/months I would have assumed some shenanigans and thought it was a faked/feigned injury done to either stall or get out of the fight. I think Fury does want this fight even if he knows he's going to struggle or it being his biggest test. The money is just too good to turn down. Gareth A Davis has a saying for why fights do or don't happen: Money, ego, timing and he's right, but money is the biggest factor. Many fighters will avoid fights if they think they will lose or struggle but every fighter also has a price. Would I get in the ring with Fury or Usyk for a few grand? Nope. Would I do it for millions? Of course.
