Two-time U.S. Open champion Curtis Strange is planning to undergo medical tests after experiencing dizziness and persistent headaches the past few weeks, the Richmond (Va.) Times-Dispatch reported.

The newspaper said Strange, 36, will be examined next week at the Mayo Clinic in Rochester, Minn.

“I’m not going to play any more tournament golf until this is taken care of,” said Strange, who withdrew from the PGA Championship at Carmel, Ind., after shooting a nine-over-par 81 in Thursday’s first round.

“It’s embarrassing and frustrating to play like that,” Strange said. “I hit only three greens in regulation. I take a practice swing and stumble over my own feet. And feeling like this, it’s kind of tough to make downhill, sidehill four-foot putts. It’s like having a bad case of jet lag day after day after day.”
