My left foot did not clip out as I fell - spd clipless pedals (the ironic part is that they are campus pedals - clip in on one side - not clip on the other). My wrist is only sprained - happily I took most of the fall on my hip - which has a massive bruise (I hadn't been paying much attention to hip/backside until I got on bike Saturday and thought - gosh this hurts - looked in a mirror and realized the problem.)
