Dani Clos will return to action for HRT at the Belgian Grand Prix, with the team confirming he will drive in first free practice again.
The Spaniard is to have his fifth outing of the season, and will take over Narain Karthikeyan's cockpit for the Friday morning session.
"Once again I have a chance to step into the car and work for the team and that fills me with satisfaction," Clos said. "Especially after having run in the events leading up to the summer break, for me it is really important to stay active and be able to continue growing alongside my teammates Pedro [de la Rosa] and Narain."
