Prosise has been dealing with ankle injuries throughout the season. The most recent flare-up happened during the team’s Nov. 9 win over the Cardinals, forcing him from the game midway. His prognosis apparently wasn’t great heading into this weekend’s game against the Falcons, prompting the team to park him on IR for the rest of the year.
Davis, a fourth-round pick of the Niners in 2015, was claimed off waivers by Seattle in May. Although he didn’t make the Week 1 cut, the Seahawks signed him to the taxi squad after releasing him. The 24-year-old had 19 carries for 50 yards in eight games for the Niners last year. He has yet to show much at the NFL level, but the Seahawks believe that he has a bit of potential.
