ORLANDO, Fla. — Tiger Woods' former swing coach confirmed in a TV interview that the besmirched golfer underwent counseling for sex addiction during his competitive absence, also offering a strong refutation to any suggestion that Woods has used performance-enhancing drugs.

Hank Haney, in his first prolonged interview since Monday's decision to leave Woods' employ, made the disclosures in a segment set to air Sunday on the Golf Channel at 6 p.m. EDT. An excerpt was available on the network's website.

Asked what the world's No. 1 golfer had been treated for during his six-week stay of inpatient counseling, Haney hesitated briefly before saying: "The only thing that I knew about was his issue with the sex addiction."

Published reports have linked Woods with more than a dozen mistresses, ranging from a New York events planner to a reality-show participant to a restaurant waitress to at least two porn stars.

"It's an ongoing day-to-day battle," Haney said, "but so far I think he's doing a really good job."

Haney also said he was present for four of Woods five blood-spinning sessions with the controversial Dr. Anthony Galea, who is under federal investigation for providing performance-enhancing drugs to athletes.

"There was never anything that went into Tiger Woods' body that didn't (first) come out of his body," Haney said.

"I can just tell you that I spent 110 days with Tiger a year for six years. I spent probably 40 to 50 nights a year at his house. I've never seen him do any (performance enhancers); he's never talked about anything."
