A few years ago, one of the players on our high school football team passed away...car crash coming home from his girl friend's house on Wednesday. The family, school, community were all a wreck. That Saturday, the team played in the State Semi Finals. The schedule was beyond anyone's control locally. The game went on with family members present and their blessing. Very emotional time...very emotional game. We get beat in that game, but there were a lot of heroics in just being able to take the field in his memory. It ended up being a fairly therapeutic experience for a lot of people.
This was obviously a much different situation then yours, but I figured I would share. I would not play the soccer game. Good luck.
