Christian Vietoris will return to the GP2 Series for this weekend's round at the Valencia street circuit.
The 22-year-old German has missed the previous two rounds after a heavy crash during the Istanbul sprint race in May caused him to suffer painful headaches. He has, however, been able to continue his DTM duties with the Persson Mercedes squad, during his spell on the single-seater sidelines due to the lesser physical demands placed on drivers compared to a GP2 car.
Alvaro Parente, who substituted for Vietoris at Racing Engineering at Barcelona and Monaco, has moved to Carlin in place of Oliver Turvey.
