Governor 's Island , New York ( CNN ) -- The `` sport of kings '' proved a bit tricky this weekend for Britain 's Prince Harry , who fell headfirst off his horse during a charity polo match in New York . The prince , who is third in line to the throne , was sending the ball downfield when he overbalanced . He pitched forward , keeping hold of the reins with one hand while he rolled to land on his backside . He did not appear to be hurt . The 25-year-old prince walked backed to his horse and remounted to cheers from the crowd on the baking hot day on Governor 's Island . Harry was playing in the Veuve Clicqout Polo Classic in aid of a charity he co-founded to help AIDS victims in the tiny African nation of Lesotho in South Africa . Prince Seeiso of Lesotho is the other co-founder of the charity , Sentebale . Harry , the younger son of Prince Charles and the late Diana , Princess of Wales , has faced more dangerous situations than a charity polo match -- he served for two months as an Army officer in Afghanistan , and is now training to be a military helicopter pilot . CNN 's Andrea Mineo contributed to this report .
