A hip drop tackle is a specific type of tackle in football that involves the defender wrapping up the runner and then deliberately pinning the runners leg under the defenders body weight while pulling them backward. This type of tackle is dangerous because it can cause serious injury to the runners legs, ankles, and knees. The NFL is considering banning the hip drop tackle due to the high risk of injury it poses. The league has already banned the horse-collar tackle, which is a similar type of tackle that also increases the risk of injury. The NFL is gathering data and conducting a study on the hip-drop to make a determination.
