Five-time rowing world champion and one of New Zealand's leading Olympic medal hope Mahe Drysdale has been hit by car while training in Germany.
Rowing New Zealand chief executive Simon Peterson says the shoulder injury is not serious, but will rule Drysdale out of the World Cup regatta in Munich at the weekend.
The competition is the final build-up event to the London Olympics, which begin with women's football on 25 July, two days ahead of the opening ceremony.
Since 2011, Drysdale has reduced the amount of on-water training he does because of arthritis in his back and now cycles each day.
Peterson says Drysdale was at a roundabout earlier this week when one of his wheels was hit by a vehicle, knocking him to the ground.
He will undergo an MRI scan in Munich on Wednesday and the injury is expected to keep him off the water for about four days.
Drysdale was involved in a similar incident ahead of the World Champs in Slovenia last year, but went on to win the single sculls title.
