Rory McIlroy: Would be happy to see more stringent drug testing in golf
Rory McIlroy has defended the decision of the PGA Tour to clear Vijay Singh of using a banned substance.
The Fijian admitted earlier this year that he used deer antler spray, which contains small amounts of a growth hormone that was banned by the World Anti-Doping Agency and the PGA Tour.
Singh, who never failed a drugs test, was sanctioned on 19 February, but after he appealed the Tour contacted WADA and said in a statement that: "At that time, WADA clarified that it no longer considers the use of deer antler spray to be prohibited unless a positive test results."
Speaking at a press conference ahead of the Wells Fargo Championship, McIlroy said: "WADA made a decision which said that deer antler spray was no longer on the prohibited list so there isn't really much they can do about it.
"My stance on it is that Vijay didn't know he was doing anything wrong, and if there is no intention there I don't see any reason to unfairly punish him."
McIlroy also insisted he would be happy to undergo regular urine and blood testing similar to those experienced by his girlfriend Caroline Wozniacki on the WTA circuit.
The world No 2 was with Wozniacki in Monaco last month when they were woken at 6am by drugs testers, a situation golfers will have to get used to when the sport falls under Olympic jurisdiction from 2016.
"Most other professional athletes have to fill out a whereabouts form that is three months in advance," McIlroy added. "If we are going to be part of the Olympics it's something we're going to have to do too and I completely don't mind that at all."
PGA Tour commissioner Tim Finchem had earlier conceded the status of deer antler spray was "kind of silly."
He said: "We follow WADA on this stuff. We follow, with a few exceptions, the entire list of substances that are banned. We refer to them and defer to them really on the science of these issues as to what's on the list.
"It's not a violation of the Doping Code for you to use deer antler spray. Now, however, if we get a test and there is a level set and we test for it....but we'll be very aggressive in letting people know when that test comes around."
