Dawson's addition provides some much-needed depth at linebacker with K.J. Wright (concussion) and Bobby Wagner (hamstring) both uncertain to play Sunday against the Rams. Even if one or both players are sidelined, it's unlikely that Dawson would log substantial defensive snaps during the contest, as D.J. Alexander and Terence Garvin would be the more likely candidates to earn promotions into the starting lineup.
Dawson (arm) played on special teams in Friday's 27-10 preseason win over the Ravens.
Dawson appeared to be past the arm injury that had hindered him in practice early on in training camp. His lack of defensive snaps isn't a positive sign in terms of his odds of making the team. He spent last season on the team's practice squad and could be in line for another year as a depth option in 2017.
