SCOTTSDALE, Ariz., Jan. 30 (UPI) -- PGA golfer Vijay Singh admitted Wednesday he used a controversial deer antler spray but said he didn't know it contained a banned growth hormone.
Singh and Baltimore Ravens linebacker Ray Lewis were named in a Sports Illustrated story this week as users of the spray -- derived from fast-growing deer antler velvet and containing small amounts of IGF-1, which is banned by the NFL and the PGA Tour.
