NEWTOWN SQUARE, Pennsylvania (AP) — Tiger Woods is using crutches and wearing a protective boot on his left leg to make sure he’s healthy enough to play the US Open.

Woods doubts he’ll play the Memorial next week in Dublin, Ohio, but expects he’ll be “ready to go” for the US Open June 16-19 at Congressional.

Woods is counting on proper treatment and rehabilitation. He is bothered by pain in his left knee, left Achilles’ tendon, tightening in his calf, and sore lower back. He says doctors have not mentioned leg surgery.

“I’ve had four surgeries on it,” Woods said yesterday. “Obviously, it’s not what it was when I was little.”

Woods said he’ll start training by the end of next week. How his leg responds will determine when he can start hitting balls again — all but ruling out the Memorial.

That means Woods would go to the US Open with little competition, although this is nothing new for him. In 2008, he had arthroscopic surgery after the Masters and didn’t play again until the US Open. Doctors discovered a double stress fracture in his left tibia in the weeks before the major. Going against his doctor’s advice, Woods not only played the US Open, he won it at Torrey Pines in a 19-hole playoff.

Now, he says his left leg is not nearly as bad as it was then. His golf, however, is a different story.

In the 11 tournaments Woods played before the US Open, he won eight times, was runner-up twice and didn’t finish out of the top five. In the 11 tournaments before this US Open, he has only five finishes in the top 10.

Woods said he was more worried about his health in 2008.

“I’m a lot better off,” Woods said. “I feel that in the next week or so, I can start getting back toward that and start practising pain free. That’s where I’m at.”
