"I believe at this time that it is in both of our best interests for me to step aside as Tiger's coach," Haney said in a statement to The Golf Channel, according to Golf.com. "I will always look back upon our past half dozen years together as my best days in professional golf."
Haney did not give a particular reason, saying it was just time to move on. He told KTCK-AM sports radio in Dallas on Tuesday that he had resigned via text message.
"I texted him last night [that I was leaving], and he texted me back," Haney told the station. "We went back and forth for a while, but he had his kids last night and couldn't talk. We are going to talk later today."
Haney insisted he wasn't fired. He also predicted that Woods will return to top form after his sex scandal. "As we all know, Tiger has been through a lot in the past six months," he said, "and I really believe that given the chance, mind free and injury free, we will all see Tiger Woods play once again like we all know he can."
