Perez and Petrov updates

Sauber's Sergio Perez will remain in hospital for further tests following his nasty crash in practice on Saturday.

Perez hit the bump coming out of the famous Monte Carlo tunnel, which made his car snap right into the barrier. As his car hurtled towards the Nouvelle Chicane, everyone hoped he would shoot down the left hand side like Nico Rosberg on Thursday or perhaps down the right hand side like David Coulthard a few years ago.

But unfortunately he hit the barriers on the exit of the chicane side on, in a very similar incident which left Karl Wendlinger in a coma following the 1994 race.

Thankfully over the past decade the safety of the cars with more protection around the cockpit and the barriers helped to absorb the impact and Perez only suffered concussion and a bruised leg.

'He has concussion and a bruised thigh and will be kept in for at least another day.'

'Sergio is doing very well, he had a good night and is chatting away.' Sauber chief executive officer Monisha Kaltenborn told the BBC.

Perez remained in hospital last night for further observations and will have a second brain scan on later today.

Renault's Vitaly Petrov has been released from hospital following the crash that brought out the red flag towards the end of Sunday's Grand Prix.

The incident which involved Force India's Adrian Sutil, Toro Rosso's Jaime Alguersuari and McLaren's Lewis Hamilton was a chain of events that happened just in front of the leading trio of Vettel, Alonso and Button.

Sutil's Force India had a puncture after he brushed the wall, this led to Hamilton taking avoiding action, which resulted in Alguersuari crashing into the back of him, while Petrov was left with no where to go as his Renault hit the barriers at the Swimming Pool complex.

'I'm fine. It's been a big crash but I'm OK, I would like to thank all my fans for all their well wishes, the medical teams at the circuit, the hospital for their efficient and friendly assistance, and the team for their concern.' Petrov said after leaving hospital.

'It was quite a big impact and I could not feel my legs very well after the crash.

'I thought it was best for the medical team to assist with removing me from the car as it was difficult for me to move and my legs were trapped in the cockpit. I did not lose consciousness but I was in quite a lot of pain when I was inside the car.'

Petrov believes he will be fit to race in a couple of weeks time in Canada, while Perez will have to wait to see if he will be cleared by the FIA medical team.
