Williams have confirmed that Felipe Massa is undergoing "precautionary checks" after a high-speed crash towards the end of the Canadian Grand Prix.
The Brazilian driver had raced into contention for victory as he closed the gap to the chasing pack behind long-time leader Nico Rosberg.
However, as he looked to pass Sergio Perez, his car came into the contact with the Force India driver and careered into the wall at turn one on the Gilles Villeneuve Circuit.
Massa was checked out at the medical centre after the Grand Prix before being transferred to hospital for further examinations, but the team told reporters that he was doing "OK" and Williams head of vehicle development Rob Smedley revealed the severity of the crash.
He told BBC Sport: "Felipe Massa has been checked out in the medical centre and doesn't seem to be having many problems. There was 27G in the car so it was a high impact and he has now gone for precautionary checks. He is fairly miffed at the moment.
"With Felipe, we were not looking too bad. We were on for chasing Sergio Perez which would have got us up to fourth but we couldn't get at the Red Bulls. We had some problems with Valtteri Bottas.
"You look back at what you have done badly and we will make sure we don't do it again. We will pick ourselves up and dust ourselves off. We have a good car and are heading in the right direction."
The race was won by Red Bull's Daniel Ricciardo, thus ending the Mercedes run of victories.
