Michelle Wie injured her wrist in a fall while running and is wearing a hard cast that will keep her away from golf for at least a month, a family spokesman said yesterday.

Spokesman Jesse Derris said the 17-year-old injured her left wrist this week and that her doctors expect it will take four to six weeks to heal.

He said surgery wouldn't be necessary on the injury, while declining to give further details.

Wie already had an injured right wrist, sustained while hitting a shot off a cart path during the women's Samsung World Championship last October. She missed the cut by 14 strokes in last month's Sony Open, her worst performance in four straight appearances in the men's PGA Tour event in her hometown.

Wie's right wrist was tightly wrapped at the Sony Open.

"Michelle's playing schedule will be altered as needed to allow the injury to fully heal," he said.

Wie wasn't planning to play in either the SBS Open or the Fields Open the next two weeks in Honolulu when the LPGA Tour season gets under way.

But the injury raises questions whether she will recover in time for the Kraft Nabisco Championship, the first LPGA major of the year that starts March 29.

A year ago, Wie was one shot behind when she faced a 25-foot chip from just off the 18th green at Nabisco. She hit it 10 feet by, then missed the birdie putt that would have allowed her to join a playoff.

Wie started 2006 strong. After missing the Sony Open cut by four shots despite shooting a 68 the second day, she contended for the title in her first five LPGA medal play events. She eventually finished with a second, three thirds and a fifth.

She finished out of the top 10 in her final two LPGA Tour starts and has missed the cut in her last four appearances against the men.
