Hank Haney, Tiger Woods' former swing coach, reportedly says he never saw any indication that his star pupil used performance-enhancing drugs.

Haney's full interview airs at 6 p.m. ET Sunday on the Golf Channel, and the New York Daily News reports that Haney responds to a poll by Sports Illustrated that had 24 percent of PGA Tour players surveyed saying they believe Woods has taken PEDs.

"I truly believe those (rumors) are 100 percent false. People that say otherwise are just starting rumors. It's based on no facts at all."

Haney, who resigned as Woods' coach last week, goes on to say, "There's a lot of jealousy out there and people will say things, but I will just tell you that I spent 110 days a year with Tiger for six years. I spent probably 40 to 50 nights a year at his house. I've never seen him do anything. He's never talked about anything," Haney said.

Questions about PEDs came up when it became known that Dr. Anthony Galea, who is under federal investigation for prescribing PEDs, treated Woods. Haney confirms what Woods has said about those treatments: They were perfectly legal treatments using a blood spinning technique.

"I was there and watched the whole procedure," Haney said. "There was never anything that went into Tiger Woods' body that didn't come out of his body. They take the blood out, they spin it, they inject the plasma back in. I totally believe that Tiger Woods has never taken any performance-enhancing drugs."
