Hmmmm, 'maybe'.
I'm fairly sure the PGA Tour has some sort of morality clause. John Daly was 'punished' by the PGA Tour for drinking. Being an alcoholic he's not to have a drop of booze (I can't recall the specifics).
Even if the PGA Tour punts on Tiger and gives him a pass, there's still the spectators. Every hole is surrounded by them from Tee to Green. And you can bet the rent that when Tiger gets ready to swing or putt, many spectators will NOT observe that 'Quite Sign' the officials hold up and give him a good share of verbal abuse / cat-calls.
And these Pros are so focused during their swing that even a camera shutter clicking throws off their swing and they slice, shank or hook the ball. And what Tiger will be getting will for sure be a lot worse than a 'click'. Especially from the women and 'ex' die hard Tiger fans who are now crushed by his slutty actions.
So either way he's screwed. (no pun intended)
He could always charge exorbitant fees for lessons or write a book.
