Tiger Woods has withdrawn from this month's Open Championship at Royal Troon.

The 14-time major winner has been struggling with a back problem and hasn't played since August.

Last week Woods said he was making progress, but he wasn't ready to play four days in a row.

He has not played this having undergone back surgery last year. He has gone down the surgical route three times since 2014.

By not playing at Royal Troon, Woods will miss a third straight major for the first time in his professional career.

"I keep getting physically better. I just hope that everything clicks in and I can do it sooner rather than later," he said a week ago.

"I guess I still need to get in golf shape. It's about four, five days in a row.

"I just need to get to where strength-wise I can handle the workload of playing out here on a weekly basis, practising after round, not having to go ice my back and all that kind of stuff.

"I'm not quite there yet. I've pushed through a lot of injuries and rehabs before. I'm trying to do it correctly at this time."
