NFL meeting to ban hip drop tackles.. (Update: Now banned)

I understand the spirit of the proposed rule as this has caused some gruesome injuries. I'd like to see some videos of hip drop tackles on the ankle where no injury occurred. It looks like it would only be a foul when you hip drop into the lower leg. In some of the videos posted in this thread, it showed the hip landing on the turf, not the leg, which wouldn't be a penalty.
