Former Open champion John Daly, no stranger to controversy himself, has urged Vijay Singh to drop his lawsuit against the PGA Tour for "reckless administration and implementation" of its anti-doping program.
A week after the Tour dropped their case against him for the use of deer antler spray, Singh yesterday filed a lawsuit in New York claiming their actions left him "humiliated, ashamed, ridiculed, scorned and emotionally distraught."
It came the day before the $6million Players Championship got underway at PGA Tour headquarters at Sawgrass today and led Daly to write on Twitter: "VJ don't do this, horrible advice, you got off, take it from me, not worth it #friendlyadvice."
Singh, 50, admitted in January to using deer antler spray, which was said to contain small amounts of IGF-1 (Insulin-like Growth Factor-1), a growth hormone which at the time was on the World Anti-Doping Agency and PGA Tour list of prohibited substances.
The three-time major winner told Sports Illustrated he used the spray "every couple of hours...every day" and was "looking forward to some change in my body."
Although he had not failed a test - and no test even exists - that was treated as a violation of the Tour's anti-doping program and Singh, according to the lawsuit, was suspended for 90 days on 19 February.
However, after he appealed, the lawsuit claims that Singh informed the PGA Tour on 24 April of the "scientific realities of IGF-1," stating that the substance labelled IGF-1 in the spray had been misnamed, was biologically inactive and so weak as to be nothing more than a placebo.
Six days later, the case against Singh was dropped, with the World Anti-Doping Agency telling the PGA Tour that "it no longer considers the use of deer antler spray to be prohibited unless a positive test results."
PGA Tour commissioner Tim Finchem said such spray would no longer be on the prohibited substances list and that using it resulted in amounts in the body that "couldn't be distinguished, even if you had an accurate test, with the amounts that you might take into your body from milk."
According to the suit, children suffering from growth failure may be prescribed a drug known as Increlex, which is a form IGF-1. It reportedly must be injected to be effective and contains 10 million nanograms per millilitre. The suit states that the spray contains just 60 nanograms per millilitre.
The suit states that: "Singh seeks damages for the PGA Tour's reckless administration and implementation of its Anti-Doping Program.
"After exposing Singh, one of the PGA Tour's most respected and hardest working golfers, to public humiliation and ridicule for months, and forcing Singh to perform the type of scientific analyses and review that the PGA TOUR was responsible for performing, the PGA Tour finally admitted that the grounds on which it sought to impose discipline were specious and unsupportable."
The PGA Tour declined to comment.
