Nordeus has already implemented a funny change to restrict number of injuries within a match to 1 and avoid players repeatedly injured within a short period. You can search details of this from previous announcement.

I feel sorry if these injuries bordered you. But your case is not a injury crisis at all. You will understand this if you will gain more experience in this game.

In my experience, injuries sometimes suddenly arrive as a storm and sometimes disappear a while within a period. You can find description of injury pattern from different managers in previous posts in this forum as this used to be hottest topic in this forum.

FYI, as I remember my team used to have about 14 injuries and players were out for total more than 50 days within 1 week.
