(Reuters) - Four-time major winner Rory McIlroy has voiced support for the PGA Tour's drug-testing reforms that introduce blood screening and revise the list of banned substances to match the World Anti-Doping Agency's directory for the 2017-18 season.
Last July, the 28-year-old Briton expressed concern over the lack of regular drug testing in golf compared with other Olympic sports and advocated the introduction of blood testing.
