VIJAY SINGH UNDER PGA SCRUTINY FOR ALLEGED USE OF BANNED SUPPLEMENT

FROM THE BBC SPORT.COM WEBSITE

US PGA Tour officials are to investigate claims that former world number one Vijay Singh used a banned supplement.

An article by respected American magazine Sports Illustrated  claims Singh admits using "Deer Antler Spray".
It is manufactured by the controversial company Sports with Alternatives to Steroids (SWATS).
In promotional material, the firm claims the substance contains IGF-1, a natural, anabolic hormone that stimulates muscle growth.
The SI report says Singh ordered quantities of the spray last November and quotes the three-time major champion claiming he takes it: "Every couple of hours, every day."
"I'm looking forward to some change in my body," Singh is quoted as saying. "It's really hard to feel the difference if you're only doing it for a couple of months."
There has been no comment from the 49-year-old Florida-based Fijian since the publication of the story. He is due to compete in the US Tour event in Phoenix which starts on Thursday.
US PGA Tour senior vice president of communications Ty Votaw said: "We have just been made aware of the report but we haven't had a chance to review it."
The substance is on the banned list and in 2011 former Open Champion Mark Calcavecchia ended his promotional link with the product after being warned by the Tour.
Singh has won the PGA Championship on two occasions, in 1998 and 2004, and also won the Masters in 2000.
