Robert Kubica broke his right leg in a spectacular crash Sunday near the midway point of the Canadian Grand Prix.
Kubica, a rising star of Formula One, was racing with the Toyota of Jarno Trulli and the Ferrari of Felipe Massa when he suddenly veered off course into the grass as they drove toward the hairpin.
Kubica's BMW Sauber slammed hard into the inside concrete wall, somersaulted across the track in a shower of debris, hit the outside wall and came to rest with what was left of his car on its side.
Medical personnel removed Kubica from the car and took him to the track medical facility before transferring him by helicopter to a Montreal hospital. Team officials said Kubica never lost consciousness.
