Most coaches, not all, require players to practice the day before the game. If the player was suspended on a Thursday and a game on Friday, I would assume that he wouldn't practice and wouldn't play. If he was suspended on a Friday, I could see him playing on a Monday night after practice on the weekend.
All of this is assuming the coach is "ok" with having the student be suspended in the first place. I think the fact that your player was suspended from school is the bigger issue here. If I have a kid that was suspended, normally there would be team consequences that would have to be in place to begin with.
