Professional golfer Vijay Singh shocked the sporting world when he filed suit against the PGA Tour on Wednesday for "public humiliation and ridicule" resulting from the organization's investigation of his use of deer antler spray as a possible doping violation.

Last week, the Tour cleared Singh of any violation in association with the spray. His suit, filed in the Supreme Court of the State of New York, claims the Tour violated its duty of care and good faith by even beginning the investigation that lasted 12 weeks.

Singh is from Fiji and began his professional golfing career in 1982. Deer antler spray and pills contain IGF-1, a hormone that is thought to help muscles recover. When the Tour found out that Singh was using the spray, it sanctioned the golfer and launched a full investigation to ensure that the spray was not aiding Singh with an unfair advantage over his fellow golfers.

The suit came as a surprise on the eve of the PGA Tour's flagship event, The Player's Championship. But Singh made clear that the sole purpose of the suit is to restore his reputation in the sporting world. The golfer, from Fiji, began his professional golfing career in 1982.

"I am proud of my achievement, my work ethic and the way I live my life," said Singh. "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."
