I think there is definitely some relation between RED PACK and injury...
It has been proven that the day on which you receive your treatment pack from the medic team, injury will be waiting for you......
Plus I really believe in the multiple of 50 theory...As you will cross 35+ the game will prevent you from reaching 50...And so on in multiple of 50......
Or may be the injury frequency rate is so high that we can easily establish a relation as we want......
