assuming you meant to type you "sat" him for 2 games and he was fine. How did you do this? Everytime I swap out a player for someone else they go back to my collection. There's no reserve, or IR, or bench spot to fillm and none of my players ever heal.
If you have in fact had a player recover from injury without using a card, can you please explain how you sat him without removing him from the roster and thereby allowed him to heal? You didn't just swap him out for another player because I've tried that a dozen times and no healing occurs when I play the next game.
