Tiger Woods could be in danger of missing out on next month's Augusta Masters.

The World Number 1 failed to finish the Honda Classic yesterday, withdrawing during his final round at Palm Beach after complaining of back spasms.

Woods had hit an impressive 65 on Saturday before he was forced off the course.

Rory McIlroy had to settle for a joint second place finish yesterday, after losing out to Russell Henley in a four-way play-off, but the Ulsterman has moved up two places in the rankings to 6th place.
