He didn't just have it, he's already hitting balls. I would guess they stagger the announcement with a reasonable buffer, I dunno, so the paparazzi don't go looking for him at the hospitals? I dunno.
Tiger Woods has another back surgery
Tiger Woods has undergone his fifth back surgery and will miss at least two tournaments, with the rest of his schedule being an unknown. But...
Even so, IMHO he won't have enough preparation time. More significantly, I think for his future sakes, he should not compete in professional golf. He achieved more than anyone else can (I don't want to hear about 18 majors).
