The Australian tweeted on Thursday: "Unfortunately I won't be able to start the Women's Tour of Scotland. Doctor's orders after sustaining a concussion at the RideLondon Classique. Disappointed to miss the first edition of the race. Good luck to all riders and organisers. Looking forward to following along, albeit from my couch."

"The MRI scan proved that my intervertebral disc is damaged, which causes shooting pains," she explained. "We're now looking at a possible treatment plan. In any case, I will no longer be able to race this season."
In good news for the 24-year-old Dutchwoman, however, she's been handed a contract extension midway through what is her first season with CCC-Liv.
"I'm comfortable at CCC-Liv, and am therefore very happy with this contract extension. I'm now being cautious with my back, so that I can start training again soon and lay a good foundation this winter for the next season.

"I was greatly welcomed at CCC-Liv, and quickly felt at home and found my place there," she said. "Even though it was difficult to express my expectations in advance, I was able to show myself well on several occasions, including at the races in Drenthe and at the Dutch national championships.
"With the RideLondon Classique, I had my first race of the last racing block, so it's a shame that it's ending now."
Cyclingnews is the world's leader in English-language coverage of professional cycling. Started in 1995 by University of Newcastle professor Bill Mitchell, the site was one of the first to provide breaking news and results over the internet in English. The site was purchased by Knapp Communications in 1999, and owner Gerard Knapp built it into the definitive voice of pro cycling. Since then, major publishing house Future PLC has owned the site and expanded it to include top features, news, results, photos and tech reporting. The site continues to be the most comprehensive and authoritative English voice in professional cycling.
