I posted this on another thread but prob more relevant here:
I did exactly the same as Jay in my last game before Xmas. I jumped high for a ball to control it, came down on one leg and my knee gave way. I ruptured my medial ligaments. Seeing him do that today brought back some bad memories and made me wince.
I re-did mine last weekend, stupidly having a kick around with my 10yr old son. I've now torn my ACL aswell. Bad times!
Reckon Jay's medical care might be a bit better than mine though but if be astonished if he's back playing before preseason. Hope I'm wrong.
If I was a betting man, I'd say medial ligaments and back for pre-season.
