Sports injuries are injuries that occur in athletic activities. In many cases, these types of injuries are often due to overuse or acute trauma of a part of the body when participating in a certain activity. For example, runner's knee is a painful condition generally associated with running, while tennis elbow is a form of repetitive stress injury at the elbow. Other types of injuries can be caused by a hard contact with something. This can often cause a broken bone or torn ligament or tendon

Injuries are a common occurrence in professional sports and most teams have a staff of Athletic Trainers and close connections to the medical community. Controversy has arisen at times when teams have made decisions that could threaten a players long-term health for short term gain.

Sports injuries can be broadly classified as either traumatic or overuse injuries. Traumatic injuries account for most injuries in contact sports such as Association football, rugby league, rugby union, Australian rules football, Gaelic football and American football because of the dynamic and high collision nature of these sports. These injuries range from bruises and muscle strains, to fractures and head injuries.
