Boassan Hagen, an ever present fixture in the Team Sky squad since their Tour de France début in 2010, had ridden the Giro d'Italia in May. Although never slated for a automatic place for the Tour de France, Boasson Hagen would have been a strong candidate for team's possible long list selection. He will now miss this weekend's national championships as well as the Tour.
"I had some rest after the Giro and when I started training again unfortunately an Achilles problem has flared up. We hoped it was getting better but it became an issue again at Route du Sud," he said on the team's website.
"I would really like to have ridden the Norwegian national championships. They are always a proud moment for me but the important thing is to make sure I fully recover and focus on the rest of the season, hopefully starting with the Tour of Poland in August."
"I've raced at the Tour de France every year since I've joined Team Sky," he added. "Obviously I would love to be competing there and it's tough to know I won't be in the team – but I also need to think about the rest of the season by concentrating on making a full recovery and racing well later in the year."
Boasson Hagen will now focus on the Tour of Pologne and results in the second half of the season. He will also need to decide his future with some level of uncertainty over whether he will remain with Team Sky. The Team has not confirmed if the Norwegian has signed a contract extension with the team with his current deal ending this season.
Team Sky is expected to name their Tour de France in the next few days with the squad built around defending champion Chris Froome.
