You cannot miss any school in order to practice or play in a game. You must pre-arrange missing class in order to participate. If practice is missed too frequently, you will be suspended from game activity, and may be asked to reconsider playing football. If a player is injured he must first tell a coach and see the trainer. If the injury cause you to not be able to participate in practice, you are still expected to be at every practice.
Class is something that is hard to define, but easy to recognize.
It is having humility, poise, confidence, and above all, tremendous pride. Class people handle victory and defeat in the same way - graciously, with their heads held high. They do not brag in victory, or make excuses in defeat. Class always shows, whether you win or lose. If you have class, you do not need much of anything else.
