Former DTM champion Mattias Ekstrom faces a race against time to be ready for the new season after breaking his wrist at an Audi training camp.
The 32-year-old suffered the injury after falling while playing volleyball with his team-mates. Audi¹s doctors are optimistic that the Swede will be fit for the DTM season opener at Hockenheim on May 1, but they have admitted that time will be tight to get him back in shape.
Audi team physician Dr Christian John said: "Mattias must wear a cast for about four weeks. Afterwards he can start training again to build up the muscles.
"We all hope that he recovers well and Mattias can line up on the grid at Hockenheim."
Audi Sport boss Wolfgang Ullrich, who always attends the training camp with the drivers, added: "We wish Mattias all the best and a rapid recovery.
"I'm convinced that he will do everything possible to be absolutely ready to go for Hockenheim. We'll give all the support he requires in the process."
Ekstrom's injury will not prove much of a setback for Audi's pre-season testing. DTM teams are operating a restricted test plan this winter, as the development of the cars has been frozen since the middle of 2009.
