It was officially an ACL for the first injury, then he came back for a month or so, and then he got this second injury, the dislocated knee cap, no ?I’m dubious about the dislocated knee cap diagnosis. That type of injury is usually just a few weeks out. He may well have dislocated his knee in addition to another injury but to be out for over a year it was clearly a far more serious injury
So he has had at least one ACL and seemed to come back as good as ever.
Or my memory might be playing tricks on me, won't rule that one out
