1. A team player that is not able to play a scheduled match must notify their team captain as soon as possible. The team captain is responsible for finding a suitable substitute.  If  a suitable substitute is not available, the two  players who are not the original computer generated Team Captain rotate end to end. ( EXCEPTION: Only in the case where the lowest rated player on the team is missing, the team captain will designate one of the 4 player positions on the court as the position that player would be at if the player was present. At that position the higher rated rotating players would play only one ball and then carry the other ball back to the other end.) The original computer generated Team Captains are not allowed to rotate. If two players are missing, at least one substitute must be found or standard rules apply. A Mixed League team must have at least one man and one woman playing in a match.

2. Team captains when selecting substitutes must select from the captain's substitute group list by choosing a player that is not playing that day in the same group as the missing player or from any group below that missing player's group. Players above that missing player's group can not substitute.

3. A person may substitute in a league that he/she is playing in if they are not scheduled to play that day, i.e., bye week players or eliminated tournament players can sub in their league.

4. Although husband and wife cannot be assigned to the same team, they can substitute on each others team or both can substitute together on another team.

5. People who signed up for the waiting list to be on a team and have been assigned a rating will be placed in the substitution list and may be called to substitute. Permanent replacements for team members will be chosen by the committee from the waiting list. Temporary Inactive players who are able to play and Substitutes are noted in the list and may be used as substitutes.

6. Late arriving team players or substitutes may enter the game at any time between frames.

7. If a player is unable to continue playing for any reason, a substitute may replace the player between frames or games. A substitute can be asked to play 1, 2, or all games, however, if a substitute is playing and the missing  player returns before the match is over, the substitute cannot be replaced unless it was previously agreed to by the substitute. Once a player has agreed to substitute, another substitute may not replace the initial substitute without the initial substitute asking to be replaced.
