How many players can a Masters Championships team use, and how do substitutions work?

• Team entry: up to 18 players (listed with shirt numbers 1 to 99 and dates of birth), within a total list of up to 25 participants including team officials.
• In a match: a team may use a maximum of 18 players, of whom no more than 16 can be field players. A Masters team is permitted up to 16 field players plus one or two goalkeepers wearing full protective equipment.
• Starting lineup: 11 players on the field, with up to 7 starting on the team bench.
• Changes to the entry list: amendments to players must be given in writing to the Tournament Director by 12:00 (local time) on the day before the first match, or at the Event Briefing if that is later. After that deadline no further changes to listed players are accepted.
• Substitutions: made as specified in the Rules of Hockey and the regulations, from the players named in the Match Report, under the supervision of the Technical Officer. A substituted player must go to the team bench.
