Prince William (search) fell from his horse as he and his younger brother, Prince Harry, took to the polo field for a charity match Saturday in aid of victims of the Asian tsunami.

The princes, who organized the charity match, led opposing teams onto the field at the Longdole Polo Club (search) in western England. Afterward, players and guests were invited to join William, 22, and Harry, 20, for tea.

Prince William wasn't hurt by his fall and quickly remounted and plunged back into action. But his team lost 12 goals to 7.

"It was just a bit of a slip and he was fine," said Matt Cudmore, one of Prince William's teammates. "We had a bit of a joke about it, and he got back on."

The sons of Prince Charles and Princess Diana (search) said they were moved by the plight of victims of the Dec. 26 natural disaster that killed more than 170,000 people.

Ticket sales for the match raised about $50,000 for the Tsunami Earthquake Appeal. Both princes have made private donations for relief efforts.
