I am a baseball coach/manager. In my stepson's baseball league, another team has a child (these are pony league players - 13 & 14) who has some arm problems. I know he has had an MRI (know the MRI tech) and also that his doctor instructed him never to pitch again. The coach and parents are aware of this too - yet the coach still pitches him in games. Other parents discuss this problem, yet no one seems willing to step up and do something about this. Since I know the story, would it be ethical if I anonymously informed the league? There may be a potential liability issue at stake here too. This kid is going to ruin his arm before he gets to high school.
I am also trying to balance the confidentiality of the medical relationship vs. the kid's welfare. Should I even be considering this?
