CHARLOTTE-Fiji's Vijay Singh will not be suspended by the US PGA Tour for doping as a result of using a deer antler spray known to contain a prohibited growth-enhancing substance. Tour commissioner Tim Finchem announced the decision on Tuesday after Singh had appealed a sanction brought against him by the tour after he admitted to using the deer antler spray in a January story in Sports Illustrated. The spray contained IGF-1, a substance listed on the World Anti-Doping Agency (WADA) and PGA Tour prohibitive lists and one the tour had warned players against using in August of 2011. While there is no blood test for IGF-1, PGA policy allows for a violation without a positive test if a player admits using a banned substance. –AFP
