Lions RB Ty Johnson was knocked out of Sunday's game in Chicago with a concussion. His absence leaves Detroit with RBs J.D. McKissic and Paul Perkins.

Andy Vasquez of NorthJersey.com projects RB Ty Johnson as a cut in his admittedly "far too early" 53-player roster projection. "[Tevin] Coleman will likely get the majority of the snaps, but there will be plenty of opportunities for [Michael] Carter and another young back," Vasquez writes. "[Josh] Adams, [La'Mical] Perine and Johnson will battle for the final two spots at this position." We're not particularly excited about any player in what figures to line up as a committee but will be tracking the competition through summer.
