Question about Wilder’s right hand

I'd say he probably amplifies the injuries in the same style as Mike Tyson saying he broke his back. So we're not really sure how bad the damage is.
Also he is likely on plenty of roids to help his recovery even if it was bad, just like Conor Mac was doing recently to fix his leg bones.
Then he would be on more painkiller type gear during the fights if he did have an issue.

But probably he never really hurts his hand as bad as he makes out.

We should also remember he claimed to have exhausted his legs with the Afro-superhero suit.
