The Seahawks on Tuesday officially announced the signing of free agent cornerback Byron Maxwell while also signing running back Mike Davis to their 53-man roster.
To make room for the two on the roster, Seattle placed cornerback Richard Sherman and running back C.J. Prosise on Injured Reserve, officially ending the season for each.
Sherman suffered a season-ending Achilles injury on Thursday at Arizona and the Seahawks are bringing back Maxwell to add depth at cornerback.
Maxwell played with Seattle from 2011-14 then signed with the Eagles as a free agent in 2015 and then was traded to Miami in 2016 before being released by the Dolphins last month.
