Just from visual...it seemed more like a break of some sort. Usually with ACL/MCL tears only, there's a little more movement after the injury. Dex stopped like a stone statue and went down. Much more consistent with really bad broken bones...who knows though? Could be one of those knee joint explosions where they tear ligaments AND break bones.IDK. They sounded certain that it wasn’t. And he was taken straight to the hospital and had his leg immobilized, which seems unusual for ligament tears.
Also...not all that common to use an air cast like that for just ligament tears.
Regardless...Dex is in for a long recovery. I just hope he's able to recover. I think he was headed towards having a really good football career.
