Substitution Rules

Beginning this fall MAPLE will implement the FIFA rules pertaining to Player substitution at any stoppage in play. 
The player wishing to enter the game must be at the Center line. At a stoppage in play the Center Referee will signal for the player to enter. 
Once the player that is being subbed off leave the pitch the substituted player can enter the pitch.
Unlike FIFA there will not be a limit on player substitution.
