Tiger Woods has confirmed that he was interviewed last week by authorities investigating a Canadian doctor who has allegedly provided performance enhancing drugs. Woods said he "answered all their questions."
Dr Anthony Galea is being investigated for allegedly providing the drugs to professional sportsmen in both the United States and Canada.
"I cooperated and answered all their questions and that was it," Woods said on Thursday after shooting a first-round 73 in the AT&T National tournament.
Woods said the meeting took place in Orlando, Florida, and lasted a "couple of hours".
Woods has said his treatment by Galea consisted of platelet-enriched plasma treatments for Woods' left knee. The "blood spinning" treatment is designed to speed recovery from injuries.
Woods has denied taking any performance-enhancing drugs.
Galea, who is not licensed to practice medicine in the United States, was charged in May with conspiracy, smuggling, unlawful distribution of Human Growth Hormone and introducing the unapproved drug Actovegin into interstate commerce.
The charges are similar to those filed by Canadian authorities in October.
According to court filings, some of Galea's athlete clients received intravenous vitamin drips, others had injections of Actovegin and some received injections of HGH, banned in sports as a performance enhancer.
None of the court documents identify any athletes by name.
Woods is just one of the sportsmen treated by Galea to be interviewed by investigators.
Baseball players Jose Reyes and Carlos Beltran said earlier this year that they had been contacted in the probe.
Last Thursday Galea's former assistant, Mary Anne Catalano, pleaded guilty to one count of lying to border agents in a plea deal that could make her a key figure in the case against her former boss.
Catalano said she agreed to bring medical equipment and vials of drugs, including HGH, into the United States for Galea to use on athletes and that the doctor had told her to lie to border officers and say the supplies were for a conference.
