The first question that should be asked is when did they buy the tickets? If they bought them before they were given the schedule, then it is not really their fault. The same goes if the games got moved from a different date, all players have to go off of is what the coach has told them. You can't honestly expect your players to sit tight and do nothing, just because they play soccer, lets be for real this is not the pros. Student-Athlets must be allowed to do what they want during the time that to their knowledge is not scheduled for anything. However, if they knew there were games and they still decided to buy the tickets without the coaches approval, they should be punished.
