I'm not a doctor, and they obviously haven't done that MRI to determine the extent of the injury, but I gotta think it'll be a while. Then again, Cousins came back in less than a year. So I imagine, absolute best case scenario, he opts in to his second year (and the sign him to an extension in the off-season) and he's back by the play-offs. But he could just sit out for the entire season and I wouldn't be mad at him.
