I'm afraid to opine on things I know nothing about.
Here was my first 'shock'... they never, (to my knowledge), said anything like 'he'll be gone a while'.... on top of that he had surgery immediately. So I figure....
(here comes the good part)
I think they were told, (The Rams that is), that with his specific type of injury AND the surgery he could be ready for this coming game. I'm not saying there wasn't some 'doubt' but it sure seems to me they were confident... the doctors and the Rams.
Of course we don't know yet, and I doubt if the Rams do either... gotta be 'tested'.... to me the indications are positive for his return.
