Tiger Woods through the years
Tiger Woods bends his left knee on the seventh green during the first round of The Players Championship golf tournament Thursday May 12, 2011, Ponte Vedra Beach, Fla. Woods withdrew from the tournament after playing nine holes and injuring his knee. "I was just trying to draw that ball out there just a little bit. I pushed forward, and you know it just didn't feel good," Woods said of his first swing after a period that included no practice for 28 days. "The knee acted up and then the Achilles' followed after that and then the calf started cramping up." (Chris O'Meara/AP Photo)
