Alabama inside linebacker Dylan Moses suffered a knee injury during practice on Tuesday that will likely cause him to miss the entire season, sources told ESPN.
Moses, a Butkus Award finalist last season, was set to be the signal-caller on defense this season.
Nick Saban told ESPN earlier this month that linebacker was among the thinnest positions on the team and that the Tide could ill afford to have injuries there this season.
Alabama was already dealing with the loss of senior inside linebacker Joshua McMillon, who suffered what's believed to be a season-ending knee injury earlier this month.
