The Seahawks are slated to sign Walker to a contract, Ian Rapoport of NFL Network reports.
Walker gives Seattle a necessary third quarterback on the depth chart in advance of training camp. He'll now have an opportunity to compete for the No. 3 job behind Geno Smith and Sam Howell. Walker is among the league's more experienced depth options, as he suited up for 21 regular-season games from 2020-23.
