My thought on preseason game on incident like this, you do not play your rivals in the preseason even it's close for stuff like this happens in preseason. If you have to schedule a rival in a game, you do not dress your own star player if you could avoid it. You control your own schedule in preseason but must schedule at least 6-8 games. This usually is the type of game where you play your star player the least on 5 on 5 and give them more PP reps for chance of your own star player to survive the meaningless game. This is the type of game where coaches try to evaluate your own prospects and is the usually the hardest part of the schedule for coaches to really make the decision because not everyone will go their hardest except for young players trying to make the team is often the fool gold. Preseason games is a waste of time and if I were a coach, I wouldn't even dress them. I would use these time practicing and train them hard for 3 full weeks before giving my opponent a chance to study my own team. If I were the player, I would do away the preseason schedule if I could.
