I haven't played sports in a while, but I did wear contacts at all times when I played. That said, I had soft contacts -- I didn't have to worry about anything worse than one accidentally falling out. Thankfully, they never did fall out. On the other hand, I found out it can be REALLY hazardous to play soccer with glasses, especially when you're the shortest one on the team. Are soft contacts a possibility just for sports? Mine were a bit expensive with a 7-diopter correction plus astigmatism correction, but they were so worth not having to deal with the glasses.
