Can things get any worse for Tiger Woods? Apparently, yes. A Canadian doctor who performed a controversial medical procedure on the disgraced golfer is now under criminal investigation for drug violations on both sides of the border. Dr. Tony Galea flew to Tiger’s Florida home earlier this year to treat Woods with his platelet-rich plasma injection therapy, also known as “blood spinning.” Galea, who lives in Toronto, is well-known in the world of sports medicine for advocating the therapy, which involves spinning blood in a centrifuge and reinjecting it into injured joints in the hope of accelerating healing. In October, police arrested Galea and raided his Toronto clinic after his assistant was detained at the U.S.-Canadian border for allegedly possessing illegal drugs, including human growth hormone (HGH) and Actovegin. Galea is expected to be formally charged on Friday. His lawyer says he is innocent.
