My commute is 46-50 miles, round trip. My soccer games were always on Friday or Saturday nights. The hardest part I had was making sure I had someone lined up to bring the net, (playing goalie, I was responsible for getting the net there and hanging it). When playing indoor, I just packed my kit on the bike and got there with time to eat.
If you're riding and playing twice a week, I think your body will adjust to the new routine. Just be sure to feed the engine and stay hydrated. Eating a smart meal after your games will help you feel better the next morning.
