I support Khris' point to keep more injuries within 1 day in T11. There are many injuries in football but most of them are minor and can recover in a few days in real life. In T11, one day is approximately represent 1 week in real life. I think it is realistic.

Personally I don't think the injury not acceptable. Injury is more a problem to teams with small squad size. These teams enjoy lower overall wages. It is reasonable for them suffering in injury storm.

Maximum Squad size 22 is similar to real life football. But T11 teams do not have youth team players for temporarily use. So T11 managers have less player to choose without healing their injured players. However, unlike real life football managers, T11 managers have treatment packs. These provide an option to heal players' injuries immediately at will. So I still think injury is less severe problem comparing with that in real life.
