Tiger Woods withdrew from his own event, the AT&T National Tournament, on doctor's orders on Wednesday, saying he was still not fully recovered from knee and ankle injuries.
Woods, who has not played since pulling out of the Players' Championship last month, said on his Twitter account that he would still attend the tournament in Newtown Square, Pennsylvania but would not be playing.
