Sundby, who has won the World Cup overall and the Tour de Ski the past two seasons is confident that the injury will not affect his World Cup season.

NRK.no reports that National coach Trond Nystad says, "Martin is exercising normal and will on Thursday test whether it is appropriate for him to compete now (Beitostolen this weekend) or whether he should wait until the World Cup opening in Kuusamo the final weekend of November."
