Sports medicine is a branch of medicine that deals with physical fitness and the treatment and prevention of injuries related to sports and exercise. Although most sports teams have employed team physicians for many years, it is only since the late 20th century that sports medicine emerged as a distinct field of health care. In some countries, sports medicine is a recognized medical specialty. In the majority of countries where sports medicine is recognized and practiced, it is a physician (non-surgical) specialty, but in some, it can equally be a surgical or non-surgical medical specialty, and also a specialty field within primary care. In other contexts, the field of sports medicine encompasses the scope of both medical specialists and also allied health practitioners who work in the field of sport, such as physiotherapists, athletic trainers, podiatrists and exercise physiologists.

American football, also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.
