At Adult game on Saturday I booked a player C1 for wearing his wedding ring. Pre kick off I had undertaken my boot check and I informed all players to remove all their jewellery. I checked this was undertaken and the game commenced. Some 10 minutes into the game I saw an away team player with his wedding ring. At next stoppage in play proceeded to book him. He claimed he never heard my instructions etc but this held little sway. I am now going to email both teams ahead of the game reminding them that ALL jewellery must be removed ahead of KO. No further issues in the game with very little dissent too so sent out clear message.
