With Dane Fletcher's injury, and possible placement on injured reserve, the middle linebacker spot is just slightly “iffier” given Brandon Spikes's own issues staying healthy. Moving over from the outside will likely be rookie Dont'a Hightower (pictured, right) if Fletcher and Spikes are out. Mike Rivera, a former practice squad player, is also likely to get an opportunity. This position will likely continue to change leading up to the unveiling of the final cuts. Hightower we'll classify as an outside 'backer. Keep (2 MLBs / 38 players total): Brandon Spikes, Mike Rivera.
