COLMAR, France — Two Tour de France riders have been slightly injured in what an official suspects was an air-rifle shooting.

Organizers said on Friday that Julian Dean of New Zealand and Oscar Freire of Spain were struck along the road in northeast France during the 13th stage.

It's not certain what weapon was used, but Dean's Garmin Slipstream team thinks it was an air rifle. Team spokeswoman Marya Pongrace says Dean's right index finger was injured. He was shaken up but is expected to ride Saturday.

Details concerning Freire were not immediately available. Police are investigating.
