World number one Tiger Woods is suffering from a bulging disc in his back that will not require surgery, Golfweek magazine reported Thursday on its website.
Woods, a 14-time major champion chasing the all-time record 18 majors won by Jack Nicklaus, withdrew Tuesday due to back spasms from the Arnold Palmer Invitational, his typical fine warm-up event for next month's Masters and one that he has won eight times.
According to the report, which cited an unnamed source, the news was actually better for Woods than if he had suffered a ruptured disc, which likely would have required an operation.
Mark Steinberg, the agent for Woods, told ESPN after the report that "nothing has changed since the announcement on Tuesday," adding that Woods was resting and would be evaluated again in the next few days.
Woods has never missed the Masters since winning his first major title there in 1997. He was won four green jackets but has not taken the title at Augusta National since 2005.
