Haney said in a statement on his website Monday night that he has resigned. Woods also posted a short comment on his website Tuesday, saying that they have agreed Haney will no longer work with him.
"I would like to thank Tiger for the opportunity that I have had to work with him over the past 6-plus years. Tiger Woods has done the work to achieve a level of greatness that I believe the game of golf has never seen before and I will always appreciate the opportunity that I have had to contribute to his successes."
Haney said the decision to move on was his own and that he and Woods will always be friends.
Woods withdrew in the final round of The Player Championship with a sore neck.
There had been speculation that he was about to leave Haney, his swing coach since 2004. But Woods said earlier Monday he was working with Haney on his swing.
