Horseriding medal hopeful Zara Phillips has withdrawn from the Olympics Games because her horse Toytown is injured.
It's the second time Zara, whose grandmother is the Queen, has missed the Games because of injury to Toytown.
She said: "I am very disappointed not to have the opportunity to ride at the Olympic Games and feel that Toytown deserved his chance to go."
But she said injuries were part of horse-riding and thought the GB team still had a good chance of success.
Zara competes in three-day eventing, which is made up of cross country, show jumping and dressage - where the rider controls the horse in a series of elegant movements.
A reserve rider and horse combination will now be chosen to take her place in Beijing.
Zara's mum, Princess Anne, rode in the Montreal Olympics in 1976, while her father took gold at the Munich games in 1972.
