Olivier Pla will replace Christian Bakkerud at David Price Racing at this weekend's round of the GP2 series in Monza.
Bakkerud has been forced out of the event after continuing with his back problems. He had suffered a trapped nerve in his back earlier in the season, forcing him to retire from the Barcelona sprint race.
Although it was hoped the summer break would allow the problems to go away, Bakkerud struggled with further pain in Turkey and was unable to take the start of the two races.
"I'm disappointed that I can't race in Monza" said Bakkerud, "but I have to try and resolve this completely and the only way is to have more rest. I hope that I'll be back in the driving seat for Spa."
French driver Pla had already raced with DPR in GP2 back in 2005 and 2006, scoring two wins in his first season.
"I would like to say a big thanks to Dave Price for giving me this chance to drive with him again," he said. "I hope I can have a strong weekend and bring him and the team a good result.
"I've recently tested the 2008 GP2 car, but it will be great to be reunited with the DPR car, with which I'm familiar."
Team principal David Price added: "We're really disappointed that Christian is still suffering with his back, but we hope that he'll be ready to get back in the car for Spa.
"However, we're grateful to Olivier for stepping in at the last minute. We've all worked together before, so that should make it easier for us all. With our third place at Monza last year, perhaps we'll be able to use this experience to achieve a much needed points finish."
