Former US Ryder Cup captain Paul Azinger has admitted he feels Tiger Woods’ neck injury may well be a serious one, the Telegraph report.

Woods, who underwent three back surgeries before making a remarkable return last season, pulled out of the Arnold Palmer Invitational earlier this week due to a neck problem.

The 43-year-old is scheduled to compete at The Players Championship on Thursday, however, after withdrawing from the Orlando event last week, the 14-time major champion’s participation is now in doubt.

And Azinger, who previously claimed the PGA Championship back in 1993, shared his concern for his fellow American.

His neck issue, that’s a serious issue I feel.

Because if your neck doesn’t flow the way you want, that’s trouble. I’m hoping he just didn’t want to take a chance, but we’ll know pretty quickly if he shows up at Sawgrass.

That’s how we’ll know how serious it is. We’ll just hold our breath and hope he gets out there and plays.

In recent weeks, Northern Irishman Rory McIlroy revealed that he witnessed Woods receive treatment on his neck before and after his rounds at the WGC Mexico Championship.

And with the American seemingly struggling, Woods may well face a race against time to be fit for the Masters, which is set to get underway on April 11.
