When someone sustains an injury while participating in sports, that indicates that something unexpected has occurred. There is a risk that the conditions that lead to the initial injury could continue to pose a health hazard both to the player who sustained the initial injury as well as other players; it is essential to remove that danger. Removing the danger could require stopping the sports activity or even transporting the injured person off the field of play. While it can be dangerous to move someone who has sustained an injury, it is more important to ensure the safety of the athlete by eliminating dangers that can result in severe injuries.
