Sauber's Sergio Perez has escaped with only concussion and a sprained thigh following his violent crash today in qualifying for Sunday's F1 2011 Monaco Grand Prix.

A brief statement put out by the Swiss-based outfit read: "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.

"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."

It is not yet known if the Mexican, who qualified tenth, despite not setting a time in Q3, will be able to start tomorrow, although it seems unlikely given he suffered a head injury in the off.
