Orlando, FL. (Best E Casino) - Tiger Woods has decided to undergo season- ending knee surgery.

The Golf Channel, citing anonymous sources, reported that Woods suffered a small stress fracture in his left leg about two weeks before the U.S. Open and doctors feel that he needs ACL surgery to get back to 100 percent.

Although his playing schedule is going to put on hold, Woods will continue to make numerous appearances and fulfill his sponsor and charitable commitments over the next five to six months, according to the television station.

Woods beat Rocco Mediate on the 91st hole of the U.S. Open on Monday, ending an instant-classic major championship with a par at the 19th hole of a playoff.

The world's No. 1 player made a birdie to send the scheduled 18-hole playoff into sudden-death, then needed only a routine par at the next hole after Mediate bounced a bunker shot off the cart path and against the bleachers.

It brought to an end one of the longest U.S. Opens in history and gave Woods is 14th major championship, second all-time to Jack Nicklaus, who has 18.
