The Mexican rookie, on a hot lap, crashed heavily with three minutes remaining in qualifying bringing out the red flags.The Monte Carlo medics spent almost half an hour assisting the driver before he was taken by ambulance to a local hospital.
Initial reports were that Perez was "conscious and talking" to the medical staff while Sauber have now revealed that he has suffered a concussion and a sprained thigh.
"It was with great relief the Sauber F1 Team received the news that Sergio Perez has no serious injuries after his heavy accident in the closing minutes of the final part of qualifying for the Monaco Grand Prix," Sauber said in a statement.
"Shortly before 15:00 hrs he had crashed into the barrier after the fast tunnel section of the circuit.
"The 21-year-old Mexican was taken to the Hospital Princess Grace in Monaco from where the team received further information at 16:25 hrs.
"The doctors said Perez had suffered concussion and a sprained thigh, but no broken bones and, following a scan, they could find no further injuries.
"The reason for the accident will be investigated and the team will update the media as soon as it has any further information."
His injuries, though, mean Perez is unlikely to line-up on the starting grid for Sunday's 78-lap Monaco Grand Prix.
