Tiger Woods is driven off the course in a cart after withdrawing during the first round of the Farmers Insurance Open golf tournament Thursday, Feb. 5, 2015, in San Diego.

SAN DIEGO — In his only his second tournament of the year, Tiger Woods has widthdrawn from the Farmers Insurance Open because of an apparent back injury.

Before putting on the 12th hole — the par-3 third on the North Course at Torrey Pines — Woods had caddie Joe LaCava pick up the ball. He was 2 over through 11 holes Thursday.

Woods has said in his last two events at Isleworth in December and the Phoenix Open last week that his health was good. He had back surgery at the end of March and took four months off at the end of the year.

Woods shot a career-high 82 in the second round of the Phoenix Open and missed the cut by 12 shots.
