Jim Harbaugh announced on Monday afternoon that the team signed CB Perrish Cox. The 49ers had one roster spot open as Mario Manningham was placed on the injured reserve on Friday afternoon. Cox hinted his signing by posting a picture of himself on Instagram through his Twitter account.
Cox spent time as a special teams player in 2012 and the start of 2013 before being released by 49ers on November 13 in order to make room for Nick Moody coming off the injured reserve/designated for return list. He recently spent two brief stints with the Seattle Seahawks in November and December before being released by the team.
Carlos Rogers left the game with a small injury and Harbaugh said the cornerback is undergoing an MRI today. If Rogers is out for the wildcard game against the Packers, Eric Wright will move up to being the nickel CB.
Cox could contribute as a CB for dime packages in his second stint with the 49ers. He could also play on special teams for both coverage units and return units.
