i watched them evaluate him right after the injury, and from the little bit of time i could see his knee and the angle i had it looked to ge gapping a lot while the doc was putting it through ACL/PCL tests. that basically means he's done due to a total rupture of one or more knee ligaments. your tibia should never gap and slide back and forth to that extent. although the angle i had was not the best and i only saw it for a second so there's still hope.
