PGA Tour Commissioner Tim Finchem announced in a press conference at Quail Hollow Golf Club on Tuesday that Vijay Singh would not be suspended for using deer antler spray and the case against Singh has now been dropped.
In a Sports Illustrated article earlier this year, Singh revealed he had taken the substance, which contains IGF-1,a banned substance on the PGA Tour and other major sports leagues as set forth by the World Anti-Doping Agency (WADA). Subsequently, he released a statement that expressed his shock and anger, along with his ignorance it was prohibited.
Singh admitted he had used deer antler spray unknowingly, but there wasn’t a positive drug test, so he is in the clear. Basically, while IGF-1 is illegal, it is not a violation unless you test positive — even though there is no way of detecting the substance through blood testing.
