The Seahawks placed Homer (ribs) on injured reserve Wednesday, Bob Condotta of The Seattle Times reports.
Homer is ineligible to play in the next four games, with his next possible appearance being Oct. 30 against the Giants in Week 8. His role on passing downs could go to DeeJay Dallas, Rashaad Penny or some combination of the two; both picked up some of Homer's typical snaps in a Week 3 loss to Atlanta.
