The Tiger Woods comeback has hit yet another snag.

Playing in just his third tournament in 18 months, Woods had to withdraw from the Dubai Desert Classic with back spasms after shooting an opening round 77.

The 41-year-old golf superstar has been trying to get back into action after a series of surgeries but it looks again like his wonky back might keep his appearances to a minimum. Woods, who seemed to be moving rather gingerly around the course, insisted that he was healthy, telling reporters, “No, I wasn’t in pain at all. I was just trying to hit shots, and I wasn’t doing a very good job.”

Woods made a comeback after multiple back surgeries after a 16-month layoff, and was expected to play four times in five weeks, starting with last week’s Farmers Insurance Open at Torrey Pines, where he missed the cut. Woods failed to sink a 12-foot birdie putt on his final hole on the North Course for an even-par 72, missing the cut at the famed course for the first time in his career.

Woods does a week off before playing in back-to-back tournament in Los Angeles (Genesis Open) and Florida (Honda Classic).
