Cobblers!
If Andy chooses surgery it will be to be competitive at ATP level.
Thoughts of playing exhos when retired will not be something that he will be thinking about right now.
It's a secondary option at the moment though so let's wait and see........plenty of fight left in Andy.
I don't see what was wrong with althusser's post. He just said "he might then at least be able to do some exhos and charity matches when retired" - I don't understand your reaction to this post.
If Andy had to have surgery i.e. a hip replacement it would be very doubtful if he could recover enough to play on the ATP tour which is extremely demanding and not for someone who has undergone hip surgery.
Andy will be thinking in the longer term - so it's very possible that he might be wondering about charity matches and exhos.
We can't know what Andy thinks, it isn't possible to do that.
I'm sure he'll be thinking around the subject and as, presumably, he has the best medical advice available, his doctors and sports team will help him to make a decision. He won't even think about what we say!
