Rory McIlroy: 'I could get away with doping'

World number four golfer Rory McIlroy has slammed the lack of drug testing in the sport, claiming that he could get away with doping.

A recent report from the World Anti-Doping Agency revealed that just 507 tests were carried out on golfers in 2014 - significantly fewer than in any other Olympic sport.

McIlroy is one of a number of high-profile golfers to have pulled out of the summer Games due to concerns over the Zika virus, but he insists that drug testing in the sport needs to improve.

"I've been tested once this year but it was only a urine test," McIlroy told reporters.

"You can't really pick up HGH (human growth hormone) in a urine test, so I could use HGH and get away with it. If golf is in the Olympics it needs to improve the drug testing.

"On average, we get tested four or five times a year. It's very little compared to other Olympic sports."

The 27-year-old is currently preparing for The Open, which begins on Thursday.
