PGA Tour commissioner Tim Finchem announced on Tuesday at the Wells Fargo Championship that Vijay Singh would not be suspended for his admission earlier this year of using deer antler spray.
It was previously presumed that because IGF-1 is in deer antler spray and that is a banned substance according to the PGA Tour that Singh would be suspended.
However, because the Tour found out about Singh's transgression via his admission and not via a drug test (according to Finchem, IGF-1 is undetectable in "routine blood testing"), he wasn't liable for the results.
"At that time, WADA (World Anti-Doping Agency) clarified that it no longer considers the use of deer antler spray to be prohibited unless a positive test results."
"Based on this new information, and given WADA's lead role in interpreting the Prohibited List, the TOUR deemed it only fair to no longer treat Mr. Singh's use of deer antler spray as a violation of the TOUR's anti-doping program."
Finally he concluded with a bit of a warning:
"The PGA TOUR recognizes that the science of anti-doping is an ever evolving subject, and the TOUR will continue to work with its consultants and WADA to stay abreast of all current developments in this area. "
