Tiger Woods has split up with swing coach Sean Foley after a four-year partnership, the 14-times golf major winner said.

The former world number one is sidelined with a back injury and does not plan to play again until his World Challenge tournament in Florida in December.

"I'd like to thank Sean for his help as my coach and for his friendship," Woods told his official website. "Sean is one of the outstanding coaches in golf today and I know he will continue to be successful with the players working with him.

"With my next tournament not until my World Challenge event at Isleworth in Orlando, this is the right time to end our professional relationship."

Woods previously worked with Hank Haney and Butch Harmon before joining forces with Foley in August 2010.

The coach controversially redesigned Woods's swing but the American great has failed to win a major in their time together.

Woods has not appointed a replacement and gave no clue about when he might make a choice.
