Quote: I believe only 18 can be rostered in a game, with seven substotitions allowed. I also think that at U14 and U15 a substituted player can't come back in the half, but can return in the second half. Once substituted in the second half, they can't come back for the rest of the game.
From what i was told that may be going to change this year. Once you are subbed for your day will be done. Cant re enter.
