Greg Norman says golf's anti-doping procedures are "disgraceful" and blood testing needs to be instituted as soon as possible.

Norman cites Vijay Singh "to know the drugs issue is there." Singh acknowledged in a magazine interview in January that he'd used deer antler spray, which contains a muscle-building hormone banned by the PGA Tour. It can be detected only by blood tests.

Norman tells The Australian newspaper that if golf wants to "be serious about it and find about what's really going on, we need to do blood testing. I think it's disgraceful, to tell you the truth."

The Aussie golf great was back in his home country this weekend for his golf-course design work.
