Tiger Woods has been linked to a sports medicine physician who is under investigation for possession of illicit drugs used to enhance athlete’s performance.

The revelation has done nothing for Woods, who is scandal-hit after ongoing claims of adulteries.

The doctor, Anthony Galea, a Canadian, claims he treated Woods at his Florida home at least four times this year after he had a knee operation. Galea claimed he gave Woods the legal platelet replacement therapy – “blood spinning” – which is his specialty.

But Galea is being investigated in Canada for alleged possession of human growth hormone and the banned Actovegin, a calf blood extract, that was allegedly found in his bag at the border in September.

Calf’s blood extract – Actovegin – was reported in 2008 as allegedly being used to boost performance of the Sydney rugby league team, Manly. It is banned by the World Anti-Doping Agency if injected.

Galea has worked with top athletes, including sprinter Donovan Bailey and figure skater Patrick Chan. His lawyer said: ”There is nothing nefarious about his practice. He’s a healer. It’s not involving narcotics. It’s involving homeopathic stuff.”
