Tiger Woods' injury woes continue.
Woods withdrew from the Farmers Insurance Open on Thursday with an apparent back injury, nearly a week after posting his worst career score.
Woods was at 3-over through 11 holes on the North Course at Torrey Pines.
Woods shot an 82 last week in the second round of the Phoenix Open, his first tournament of 2015. He had back surgery last March and took four months off at the end of last year to recover.
