A dog on musher Sébastien Dos Santos Borges' team has died, Yukon Quest officials said Wednesday.

The French musher scratched from the race at the Carmacks, Yukon, checkpoint. The dead dog will be transported to Whitehorse by a race veterinarian.

Yukon Quest head veterinarian Cristina Hansen said a necropsy will be done on the animal.
