Vijay Singh on AT&T entry list

Vijay Singh, mired in a PED controversy and one day removed from his withdrawal from the Waste Management Phoenix Open, remains on the entry list for next week's AT&T Pebble Beach National Pro-Am.

The World Golf Hall of Famer cited a back injury for pulling out of this week's PGA Tour stop. It's uncertain if the three-time major champion will actually tee it up on the Monterey Peninsula.

The 49-year-old Fijian first revealed he used a deer-antler spray that is on the banned substance list in an interview with Sports Illustrated. The magazine said Singh paid one of the owners of Sports With Alternatives To Steroids $9,000 last November for the spray, hologram chips and other products.

Singh did not speak about the allegations in Phoenix, instead issuing a statement.

"In fact, when I first received the product, I reviewed the list of ingredients and did not see any prohibited substances," he said. "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."

PGA Tour spokesman Ty Votaw said the tour is "looking into the matter."

During his career, Singh has played every AT&T Pebble Beach National Pro-Am dating back to 1994. He won the event in 2004.
