A member of the HWA Mercedes team remains in hospital following an accident with Ralf Schumacher's car during DTM practice at Zandvoort on Friday.
The rear wing of Schumacher's C-coupe caught an air line as it was being driven out of its pit stall, ripping the line away from its mounting and leading to body contact with a number of members of the pit crew. Four were taken to a hospital for treatment to their injuries, although three have since been released.
One member of the team was seen lying on the ground with a cut to the forehead.
"Three have returned to the circuit, but one is still in hospital," team said. "The injuries are not major and not life-threatening, but they are still in hospital for further checks."
