Prince Charles broke his arm Thursday in a polo accident when he fell from his horse, police said.
Buckingham Palace confirmed the 41-year-old prince had broken his right arm and was being treated in a hospital.
The accident occurred during a match at Cirencester Park, Gloucestershire. It is seven miles from Highgrove, the country home of Charles and his wife, Diana, and 70 miles west of London. The princess was in London.
Charles was playing for his team, Windsor Park, when he fell 30 minutes into play.
Police Inspector Colin Handy said: "The prince slipped off his horse. He has got a nasty break above the right elbow. He is in good spirits."
