It is allowed and recommended that you should have backup players. For instance if it is a 5-person team tournament, having 6-7 players, so that one or two can substitute in the event 1 or 2 of the main players on the team are unable to arrive or play. The team captain and other members of the team who are able to play that day must speak with the Tournament emcee to make the proper arrangements.
