My question is, let's say Player X is called up on June 21, I understand that I will not be able to use him if I play on June 21, but let's say I want to play this game in July, would I be able to use the "real" player then, or are the rosters "stuck" to the day in the schedule. So that no matter when I played that particular game, I would only be able to play with the generic player.
Make sense?
