My DD was out for two months with rotator cuff/bicep tendinitis. TB coach was fine with it since she was doing PT twice per week and working on it. It was the school PE teacher who gave her crap about it, even with a doctor's note. They were going to the weight room and PE teacher was pushing her to do leg machines. Well, some of those leg machines require you to hold on/brace with your arms and it can pull on the shoulder. DH had to talk to her to get her to let DD just use the treadmill or something else during weight time. If my DD was more meek than she is, she could have really aggravated the injury because she didn't want the PE teacher (who is our head Varsity Girls' basketball coach) to be mad at her.
