Singh admits using spray

Vijay Singh has admitted using a deer antler spray, but insisted he was not aware it may contain a substance banned by the US PGA Tour.

The 49-year-old Fijian first revealed he used the spray in an interview with Sports Illustrated, which said Singh paid Sports With Alternatives To Steroids (SWATS) US dollars 9,000 (5,700) last November for the spray and other products.

Deer antler spray contains a banned performance-enhancer connected to human growth hormone.

Singh released a statement on Wednesday ahead of the Phoenix Open which said: "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 co-operating fully with their review of this matter. I will not be commenting further at this time."

Speaking before Singh's statement, Tour vice-president Ty Votaw told USA Today Sports: "As we have just been made aware of the report we have not had a chance to review it in depth, but we will be looking into it."

The Sports Illustrated article quotes former world number one Singh as saying he used the spray "every couple of hours...every day" and was "looking forward to some change in my body".

Two years ago, 1999 Open champion Mark Calcavecchia was advised to stop using such a spray, and PGA Tour spokeswoman Laura Hill said at the time: "The PGA Tour regularly warns players of the risks associated with all supplements."
