I would say no. The problem you see in a lot of mma fighters with their hands breaking is that they haven't been striking their whole lives. The bones in their hands haven't micro-fractured and rebuilt themselves hundreds maybe thousands of time from sparring or working a heavy bag without gloves.
Thing is damn near every striker in the world would be like this if they started fighting shortly after starting training. If you look at an x-ray of any boxer's hands it will show multiple fractures and a cornucopia of healed micro-fractures. It's why boxers work a heavy bag without gloves. It's why muay thai fighters will kick poles or trees.
What you are witnessing is him getting the bad version of body hardening in his hands. It won't effect his ko power but if he doesn't start the other training he will continue to suffer this particular injury.
That is not dead which can eternal lie and withs strange aeons even death may die.
