Mickens picked up a hip injury in Sunday's game against the Falcons and has been deemed questionable to return, Jenna Laine of ESPN.com reports.
Mickens has played exclusively on special teams as a kick and punt returner so far this season. He had one kick return for 19 yards before departing. Giovani Bernard and Scotty Miller already have each returned kicks in the contest and will likely continue to fill in while the 27-year-old is out.
