Injured Woods withdraws from 4th rd at Doral

Tiger Woods pulled out of the fourth round of the Cadillac Championship at Doral on Sunday with an unspecified leg injury, a worrying setback less than a month before the Masters. Former world number one Woods, who could be seen limping during the round, left the course after 11 holes, went straight to the players' parking lot and departed. Woods, a 14-time major champion, hasn't won an official event on any tour since the Australian Masters on November 15, 2009. Shortly after that he was embroiled in a sex scandal that eventually ended his marriage. His return to top form since then has been hindered by injury, including left knee and Achilles tendon injuries that he suffered at last year's Masters. They kept him out of last year's US and British Opens, but he seemed to be on the upswing with a victory in the unofficial Chevron World Challenge in December, and he carded an impressive 62 in the final round of the Honda Classic last week. Woods had said his left knee has been as strong as it's been in years.
