Matthew Upson was left on the floor, bruised and bleeding, in England's first training session at their new training HQ in Austria.
The West Ham defender fell to the ground when he took a bad knock to the head.
He was lying on the grass for several minutes while England's doctors rushed over to treat him.
Upson's freak injury occurred as the English team began their preparations for this summer's World Cup tournament in South Africa.
The incident did not turn out badly though. Upson will still be fit to play in the tournament. He walked away from the incident laughing with the rest of his England teammates.
The new training facility, based in a farming town in Austria, is supposed to help the team acclimatize to the high altitude conditions expected in South Africa.
Their first match in their World Cup group is against USA on June 11 at a height of 5,000 feet above sea level.
