The Kolles Audi team looks set to face the challenge of completing the Le Mans 24 Hours with just two drivers in the #14 R10 TDi after Narain Karthikeyan was ruled out of the race.

The Indian driver was due to line up alongside Charles Zwolsman and Andre Lotterer in the car but dislocated his shoulder while jumping over the pitwall prior to the start of the race.

While the former Formula One man will hope to try and take part in the race at some point, the likelihood is that the privateer Audi outfit will be forced to run with just Zwolsman and Lotterer sharing driving duties.
