He is not saying, however, who his next coach might be.
Haney said in a statement on his website on Monday that he has resigned.
Woods posted a short comment on his website on Tuesday that they have agreed Haney will no longer work with him.

Woods missed the cut at Quail Hollow and withdrew in the final round of The Players Championship with a sore neck. It was the first time he played consecutive tournaments without earning official money.
