Dani Clos will miss Sunday's GP2 sprint race at Spa-Francorchamps after suffering a compressed vertebrae in an opening lap crash in the feature race.
The Spaniard ran into the back of Sam Bird's ART car exiting La Source on the opening lap and was a passenger as his Racing Engineering machine was launched into the air.
Clos complained that the hit when the car slammed into the ground again had caused pain in his lower back. He was taken to hospital where his condition was diagnosed.
Racing Engineering president Alfonso de Orleans-Borbon said: "Race results don't really count when you know one of your drivers is in hospital. We all hope Dani has a quick recovery. On a positive note, he will return to racing with us soon."
