I can honestly say that in the 8 years I've been coaching I have yet to see this happen. Maybe it's the fields we play on; I don't know. We practice on some pretty rough fields. I've always taught the girls to attack the ball to take the bad bounces out of it. I'm not saying that they haven't taken a few bad hits because they have...especially in the indoor all dirt facilities. However, it was never because of the lip of grass on the field. I'm sure it will happen some time or another though.
