Damian Lillard Goes Down with Non Contact Leg Injury

[Dahlsim]

All fair points, but that wasn't the question. The question was, is his career over?

You would have to define career over.  Maybe technically over and effectively over are not the same thing. 

He may well still be playing just on the basis of his contract but effectively could be a guard that would not be playing in the league if not for the guarantees of his contract (and his name).
