Homer (calf) has been ruled out for Sunday's matchup against Washington, John Boyle of the Seahawks' official site reports.
Homer suffered the injury in the team's Week 11 matchup but was downgraded from a limited participant Thursday to no participation Friday. His absence leaves the Seahawks backfield thin, as Rashaad Penny (hamstring) has also been ruled out. As a result, Alex Collins and DeeJay Dallas will serve as the team's primary rushers.
