Uhh, he will walk with crutches in 6-8 weeks. Weight bearing in another 4-5 weeks. After that range of possibilities are wider than the Grand canyon.
As far as golf is concerned, the one thing he has going for him is that the left leg is intact (I can't find anywhere anything that says otherwise).
So, I will wager $150, he will be playing full rounds in mid 2022. How 'bout them apples?? Anyone?
This is why practice swings don't work. That clubface is probably like 20° open.
Your body "knows" you want "shaft lean" or something, so you shove the hands forward and the face stays wide open. You wouldn't do that hitting a ball - stuff would be different because you'd have to do something to square it up.
