In light of the Sports Illustrated story, the PGA Tour sent a media blast with the following statement on behalf of Vijay Singh:
While I have used deer antler spray, at no time was I aware that it may contain a substance that is banned under the PGA TOUR Anti-Doping Policy. In fact, when I first received the product, I reviewed the list of ingredients and did not see any prohibited substances. I am absolutely shocked that deer antler spray may contain a banned substance and am angry that I have put myself in this position. I have been in contact with the PGA TOUR and am cooperating fully with their review of this matter. I will not be commenting further at this time.
