Ponte Verde Beach, Fla. • Vijay Singh sued the PGA Tour on Wednesday, a week after his doping case was dropped, claiming it damaged his reputation by not doing a thorough job of researching his use of deer antler spray.
"I am proud of my achievement, my work ethic and the way I live my life," Singh said in a statement. "The PGA Tour not only treated me unfairly, but displayed a lack of professionalism that should concern every professional golfer and fan of the game."
Singh filed the lawsuit in New York, where he had a home and the tour has an office.
The 50-year-old Fijian admitted in a Sports Illustrated article in January that used deer antler spray, which was said to include an insulin-like growth hormone that was on the tour's list of banned substances. The tour sent a sample from Singh to be tested, and it returned small amounts of the IGF-1 chemical.
The lawsuit said the tour notified Singh on Feb. 19 that he was to be suspended for 90 days.
