Tiger Woods' agent Mark Steinberg is leaving the sports management firm IMG after the New York-based firm decided not to renew his contract on Tuesday.

"He is no longer with IMG," said IMG spokesman Jim Gallagher.

Woods could either stay with IMG as it restructures its golf division or decide move with Steinberg.

Woods has been represented by IMG since he turned professional in August of 1996, and three years after that Steinberg became his agent.

At a news conference near Philadelphia earlier on Tuesday to promote the At&T National tournament, Woods said he was loyal to Steinberg and IMG.

"I'm committed to both, with IMG, and Mark's my agent," Woods said. "It's been a great relationship."

Tiger to be 'ready to go' for US Open

Tiger Woods was taking no chances Tuesday, using crutches and a protective boot on his left leg in a promotional appearance, but said he expects to play at the US Open.

Woods said he doubted he would play the Memorial next week in Dublin, Ohio, a tournament hosted by Jack Nicklaus and used by many of the game's elite as a tune-up for the US Open.

But he said he expects to be "ready to go" for the second major of the season when Congressional hosts the US Open June 16-19.

"As far as being ready for Congressional, I'm trying to do everything I can," Woods said at Aronimink Golf Club, where he was promoting the upcoming AT&T National tournament. "All my docs have said it should be ready to go by then, should be good to go."

Woods said he has pain in his left knee, left Achilles tendon, tightening in his calf and a sore lower back. He hopes proper treatment and rehabilitation can solve the problems and that doctors haven't mentioned leg surgery.
