Jan. 31 (Bloomberg) -- Vijay Singh withdrew from the U.S. PGA Tour’s Phoenix Open today after saying he used deer antler spray, which contains substances banned by the world’s top golf circuit.
Singh, 49, cited a back injury for his withdrawal, the tour said on its website. The tournament’s par-3 16th hole is known for its boisterous fans, who often cheer or heckle players while on the tee.
Singh’s acknowledgment followed a Sports Illustrated article alleging that the golfer and Baltimore Ravens linebacker Ray Lewis used the product. Lewis denied the allegation yesterday at a news conference in New Orleans, where the Ravens are preparing to meet the San Francisco 49ers in the National Football League’s Super Bowl.
Singh said he was unaware that the spray contained banned substances.
“When I first received the product, I reviewed the list of ingredients and did not see any prohibited substances,” Singh, 49, said in a statement released yesterday.
Deer antler spray contains IGF-1, a substance naturally produced by the human body that’s related to growth hormone.
