The League rules for roster movement are as follows:
1. If someone, initially rostered, does not pay or show, or is injured and they are removed from the roster, you can add a player to fill his spot at any point in the session. That player must play the required number of games to be eligible for playoffs.
2. Any change made to a roster must be "claimed" to the league at least 48 hours before the game starts. This allows ample time for the league to notify everyone. This includes goalies. "Claiming" is defined as an email or text. Players showing up to games, not on the roster, that are not "claimed" 48 hours in advance will NOT be eligible to play.
