JACKSONVILLE, Fla. -- Tiger Woods has decided to get rid of Steve Williams as his caddie.

Woods announced on his website Wednesday that he and Williams, who have been together since March 1999, will no longer be working together.

"I want to express my deepest gratitude to Stevie for all his help, but I think it's time for a change," Woods said. "Stevie is an outstanding caddie and a friend and has been instrumental in many of my accomplishments. I wish him great success in the future."

Woods did not say who would replace Williams, or when he would return. Woods continues to rest and rehabilitate left leg injuries.

Williams has worked the last two majors for Adam Scott of Australia.
