The Dolphins signed free agent cornerback Richard Marshall because they needed depth at the position. But then they traded Vontae Davis for a future draft pick, putting them right back in the same spot.
So when Marshall was pulled in the second quarter because of a tight back, the Dolphins were scrambling to fill in.
With Sean Smith and backup Nolan Carroll on the edges, they had safety Jimmy Wilson playing nickel, according to Omar Kelly of the South Florida Sun-Sentinel. The only other corner on the roster was R.J. Stanford, who they claimed off waivers from Carolina.
Marshall said he hoped to be able to play this week, but running short on cover players limited them scheme-wise, and could force them to make a move to cover a spot they made themselves thin at.
