Of this there are two types, accidental injuries and intrinsic injuries. A batter who is hit by a pitch, or a football player who suffers a dislocation from contact are victims of accidental sports injuries. Such was the case with Pele ', star of the Brazilian national soccer team, who suffered a broken shinbone on purpose during the third World Cup tournament.
打擊手被投手投出的球打中、打橄欖球互撞而脫臼，甚至如「巴西國寶」足球王比利，在第三屆世界盃比賽時，被對方「惡性犯規」踢斷下腿骨等，都是因外力而受傷，屬於意外運動傷害。
