Vijay Singh successfully appealed his 2013 PGA Tour suspension for using a deer antler spray that contained an ingredient on the World Anti-Doping Agency’s banned list. (The suspension was lifted after WADA determined that the deer anter spray didn’t contain enough IGF-1 to trigger a positive test and should be removed from its list of banned substances.)
However, according to Sports Illustrated’s anonymous poll of PGA Tour players, Singh’s fellow Tour players believe he should have been suspended -- by a 64 percent to 36 percent margin. The results are based on a poll of more than 200 PGA Tour, LPGA and Champions Tour players.
Singh later sued the PGA Tour, alleging that he was treated differently that other Tour players after admitting to using the deer antler spray in a Feb. 6, 2013, Sports Illustrated article. His lawsuit is still active in New York State Supreme Court.
