Canadian sports doctor linked to golfer Tiger Woods and baseball player Alex Rodriguez pleaded guilty in a New York drug-smuggling case Wednesday.

Assistant U.S. Attorney Paul Campana told a federal judge in Buffalo that Anthony Galea, 51, of Toronto, had admitted his guilt to charges of smuggling human growth hormone and other performance-enhancing drugs into the United States, The Buffalo News reported.

Galea had been indicted for smuggling HGH, Nutropin and the calf's blood derivative Actovegin from Canada into the United States for two years starting in July 2007.

Campana said among the medic's patients were elite athletes including Woods, San Francisco 49ers linebacker Takeo Spikes and former Baltimore Ravens running back Jamal Lewis.

New York Yankees slugger Rodriguez remains the subject of a Major League Baseball investigation for his relationship with Galea, The New York Times reported.

Galea faces a sentence of 18-24 months in prison and a fine of up to $40,000, but the prosecutor said his sentence could be lessened if he cooperates in subsequent doping probes.

Defense attorney Brian Greenspan told the News Woods had one session with Galea involving only a plasma-rich platelet treatment.
