in the last 3 games, 3 of my players have gotten injured. i thought this was odd as there hasn't been another injury for any other team in my division yet. my players do not play excessive minutes (barely above 60 mins) but im guessing it has something to do with my lvl 1 doctor. but even so, probably every other team in my division also has a lvl1 doctor. am i doing anything wrong or were these injuries just bad luck?
