Homer (calf/hamstring) has been ruled out for Sunday's game in Houston, John Boyle of the Seahawks' official site reports.
After logging a limited practice Wednesday, Homer didn't get on the field at all Thursday and subsequently will miss his second contest of the season. He hasn't received much work anyway when available, with just 19 touches and 131 offensive snaps in 11 games. With Homer out, Alex Collins, Rashaad Penny and DeeJay Dallas will man the Seahawks backfield Week 14.
