Sainz's co-driver sidelined following crash.

Carlos Sainz's co-driver Luis Moya will miss rally practice today [Tuesday] and tomorrow [Wednesday] following an accident yesterday testing for this weekend's Catalunya Rally, the fourth round of the World Rally Championship.

Both Sainz and Moya were taken to hospital after their Ford Focus RS WRC hit a rock-face in the Tarragona region of eastern Spain.

Sainz according to the official Ford Rallye Sport website "received whiplash neck injuries in the incident and co-driver Moya broke a rib and lost a tooth."

Sainz told the Radio Marca website: "Something broke and we hit a wall. We don't know exactly what happened and the team is working to find out what caused it."

"Luis Moya came off worst - his back hurts because he has fractured a rib, he bit his tongue and broke a tooth, but fortunately he was not injured more seriously."

The Ford website added that "both drivers have now been released from hospital, but Moya will not be taking part in the regulation two-day practice session that starts today. A decision on whether he will be fit enough to start the rally on Thursday will be made later this week."

Meanwhile Sainz will now take part in the practice session with the assistance of substitute co-driver Marc Marti.
