Kamui Kobayashi apologised to his Sauber team after injuring a few of his mechanics during a pitstop in the British Grand Prix.
The Japanese driver braked too late during one of his pitstops and knocked down three mechanics with the right side of his car.
Sauber said two were taken to the circuit's medical centre for treatment, one for a dislocated thumb and the other for cuts and bruises. They are now back with the team.
The third mechanic suffered a bruised foot and was treated in the team's garage.
"The accident was my fault and I want to apologise to the team," said Kobayashi. "Of course I had to push hard for points, but without doubt I braked too late in the pitlane.
"The front wheels locked, I couldn't control the car, and this is how I overshot the pit box. I am terribly sorry this happened, and I hope the three mechanics I hit get well soon."
