Robert Kubica has suffered a serious crash in the Canadian Grand Prix.
The BMW Sauber appeared to clip the back of Jarno Trulli's Toyota, going off the track and on to the grass on the exit of Turn 9 on lap 27, just after a safety car restart.
The Pole's car was launched into the air and smashed into a concrete safety wall, before barrel-rolling down the track several times.
The car came to rest on its side near the hairpin at the Circuit Gilles Villeneuve, with medical crews rushing to his aid.
Kubica was taken to the medical centre, and his condition is currently unknown.
