Brady appeared to be unharmed and in good spirits as he worked out with the Patriots at their training camp.

The quarterback was driving through the city on Thursday morning, when he collided with a passenger van and a traffic signal post.

He reportedly suffered whiplash and was treated at the scene but did not require hospital treatment, while the driver of the other vehicle was cut free from the wreckage by firefighters.

But the star didn't allow the accident to shake him - he travelled straight to Gillette Stadium, where a team doctor cleared him to participate in the 'walkthrough', wearing a helmet and pads, reports the Boston Globe.

His teammate Tully Banta-Cain tells the newspaper, ""I saw him, I asked him if he was OK. He said, 'I'm fine.'""
