Tiger Woods has confirmed he will not participate in next week’s Masters, the 14-times major winner admitting his game is “not tournament ready” as he battles continuing back issues. In the latest ominous glance towards the future Woods said on Friday he remains unclear as to when he may play again.

Woods has played only three competitive rounds in 2017, the last coming before he made a Friday morning withdrawal from the Dubai Desert Classic in early February. Woods, 41, cited back spasms having underdone three surgeries on the same area in recent times.

The absence of Woods, who still plans to attend Augusta National’s champions dinner on Tuesday, will carry extra resonance as it is 20 years on from his maiden major success.
