two weeks ago I had the great pleasure of being player coach for the USA over 50 team in the inaugural FIH/IMHA Masters Indoor World Cup. The tournament was superbly run by Dirk Wellen and his organizing team in Krefeld Germany. In our 5/6 playoff game with Italy, we were trailing 2-1 with 5 minutes to go when our goalie took a blow to the shoulder. The nearby umpire stopped play. I knew that if the trainer came on for a field player, the player had to go off for a minute. I could not remember if this applied to a GK. I asked the umpire. he said it did not, so we had the trainer look at him. She checked his arm/shoulder and declared he was OK to continue. In the meantime, the other umpire came down and told his colleague that he was wrong at that our GK would have to go off. All arguments that we had asked specifically about this before getting treatment fell on deaf ears and our goalie was forced off for a minute. Our backup unfortunately conceded a goal in that time. We went to a kicking back, got one back and then had a huge sweep over the end line by an opposition defender ignored that we thought should have been a PC. Lost 3-2. Naturally went to look this up afterwards. Nothing in the indoor rules, but tournament regs have the following: http://www.fih.ch/media/8997717/fih-tournament-regulations-indoor-december-2016.pdf 9.6 No incapacity treatment is permitted on the field of play. If a player becomes incapacitated on the field of play, one of the Umpires may stop the match and assess whether or not the player requires attention: a the Umpire may authorise the registered Team Medical Doctor and / or Physiotherapist to enter the field of play; b if a team does not have such registered officials, the Umpire will authorise the on-duty Medical Officer and / or Team Manager, to enter the field of play; c if necessary, the Umpire may also authorise stretcher bearers to enter the field of play; d persons authorised to enter the field of play are required to assist and remove the player concerned from the field of play as soon as it is safe to do so. 9.7 If any person from the team bench and / or the on-duty Medical Officer enters the field of play and attends a player: a that player must leave the field of play and return to the team bench area for a minimum of one minute of playing time; b the one minute period will be managed by the Technical Officials on duty; c the player required to leave the field of play may be substituted. So the first umpire was wrong and the second guy was right. That said, how else could I have handled this issue? (memorizing tournament regs would be a start If you were part of the umpiring team, how might you have handled this issue, once incorrect information had been given?
