Former German grand prix driver and now Volkswagen's competition representative Hans-Joachim Stuck has had surgery after a head injury.

German-language reports including in the Welt, Kleine Zeitung and Express newspapers say the operation on Saturday was for a hematoma that developed after a heavy crash in an Audi R8 at the Nurburgring several weeks ago.

At another event last weekend, the VW Scirocco Cup support race at the Nurburgring, he complained of headaches, dizziness, loss of balance and nausea.

The reports say Stuck, who contested 81 races in the 70s, has been transferred from intensive care to a normal hospital ward in the German town Neuwied.

"We advised Strietzel (Stuck) after practice to consult a doctor," confirmed VW motorsport director Kris Nissen.

The marque's spokesman Stefan Moser confirmed the reports about Stuck's surgery.
