A doping scandal has rocked the Australian cycling team Orica-GreenEDGE three days before the Tour de France.
Their South African team member Daryl Impey, who made history last year as the first rider from his country to wear the Tour's famed yellow jersey, has tested positive to the banned masking agent Probenecid.
Impey was a stunning omission when Orica-GreenEDGE announced on Tuesday their team for the Tour which starts this weekend.
The test was conducted at the South African time trial championship early in February, but Impey was told about the positive test just over a week ago.
It's a blow to Orica-GreenEDGE's image as they've prided themselves on being a clean team in the post-Lance Armstrong era.
