Depending on the injury, we may still allow them to participate. For example if they broke their leg, if their doctor writes a note allowing upper body exercise we allow them to go to the fitness room for PE credit. If they MUST sit out of class, we have them write a research paper on a specific sport. Sometimes we choose the sport for them or sometimes allow them to pick.Works out pretty well until its the last day before grades are do and I'm grading a ton of research papers because they turn them in at the last minute!
