Tiger Woods dropped out of The Players Championship due to a bulging disk in his neck.
The Los Angeles Times and The Independent reported that Woods' will be undergoing an MRI to confirm the injury and its gravity.
"I've been playing through it. I can't play through it anymore," he said, visibly upset at his locker.
He added: "I'm having a hard time playing with the pain. There's tingling down my fingers."
Woods visited the PGA Tour fitness trailer for 37 minutes after being driven off the golf course. When he emerged, he walked stiffly down some stairs and into a waiting black SUV that whisked him away to an uncertain future.
He was 2-over par through six holes and trailing by 10 shots when he hit a drive 270 yards into the pine straw. After hitting out to 50 feet short of the green, he shook hands with playing partner Jason Bohn and told him he was quitting.
It's conceivable the neck was originally injured when he crashed his SUV into a fire hydrant Thanksgiving night, touching off an unprecedented sex scandal that forced him into a five-month layoff.
