Woods withdraws at Honda

World No 1 Tiger Woods pulled out of the final round of the Honda Classic on Sunday.

Woods walked off the course at PGA National after playing the opening 12 holes of his round in five-over-par, leaving him well down the field at level-par for the tournament.

It was subsequently announced that Woods had told PGA Tour officials that a back injury was the reason for his withdrawal.

Having shot a 65 on Saturday to get himself up into the top 20 at five-under for the event, Woods struggled right from the start of his final round.

He dropped five shots over the course of his first six holes, including a double-bogey at the par-five third hole, before making his only birdie of the day at the seventh.

But a further bogey would follow at the ninth as he hit the turn in 40 strokes and, after making three straight pars to start the back nine, he decided to call it quits on the 13th green.

Woods released a statement saying: "It's my lower back with spasms. It started this morning warming up."

Asked about his chances of competing at next week's WGC-Cadillac Championship at Doral, he added: "It's too early to tell. I need treatment every day until Thursday to try to calm it down and we'll see how it is."
