I'm not sure about the "giving back the trophies part", but the direct connection to the Canadian doctor under investigation by the FBI, is quite real...
"Dr. Galea said Mr. Woods was referred to him by the golfer’s agents at Cleveland-based International Management Group, who were alarmed at the slow pace of Mr. Woods’s rehabilitation after knee surgery in June 2008."
"The doctor said he flew to Orlando, Fla., at least four times to give Mr. Woods the platelet therapy at his home in Windermere, Fla., in February and March of this year. When asked for comment about Mr. "Woods’s involvement with Dr. Galea, Mark Steinberg, of I.M.G., responded in an e-mail message: “I would really ask that you guys don’t write this? If Tiger is NOT implicated, and won’t be, let’s please give the kid a break.”
"Dr. Galea’s legal problems began in late September when his assistant was stopped entering the United States from Canada. Her car was searched by border-crossing guards and authorities found Dr. Galea’s medical bag, which contained four drugs, including human growth hormone, Dr. Galea said. “It was for my own use,” he said.
