All major college football programs have athletic trainers and team doctors on the sideline, along with a group of student assistants. While coaches are expected to be aware of their players, for the medical staff, it's the top priority. Notre Dame coach Brian Kelly said his head athletic trainer, Rob Hunt, uses spotters to watch the field for injured players. Between athletic trainers, doctors and student assistants, most big-time college football programs will have around 20 people on the sideline during games who are in some way part of a medical staff. At a Clemson football game, the Tigers will have seven full-time athletic trainers and doctors on the sideline, plus another 15 student assistants. Typically, when there is a player being treated for an injury during a game that could compromise his availability, the head trainer communicates directly to the head coach.
