Such bad news about Michaelee Harris. Everywhere you turn, someone is tearing an ACL. Makes me wonder if the training and weight workouts need to be looked at. Did players in the 50s, 60s and 70s tear their ACL. Probably, but I don't recall reading about it.
Anyway, here is a cool 3D animation that shows what happens during ACL surgery, and I suspect Michaelee will something like this done: http://www.youtube.com/watch?v=Xsq0sQp6DwU. It's only about 3 minutes long and not too gory.
