Oh by the way, I've noticed that it's never good to heal up all of your injured players (even if you have the packs).
Keeping at least one injured player in your squad, tend to make the engine give you some sort of "immunity" against further injuries... Has any of you noticed this as well ?

My experience during the past 3 seasons has been, as soon as my last injured player is healed, I'm guaranteed to have another injury in the next 1 and/or 2, 3 matches. And every time I let at least one of them stay injured, I'm OK til the whole duration of his injury.
If I heal him up, I'm guaranteed again to get someone else brake something during the next 2 days...

It really can't be a coincidence.
