Seals-Jones (hip) was listed as a non-participant on Thursday's practice report.
Seals-Jones dinged his hip in a Week 10 win against the Buccaneers and hasn't been spotted on the field since then, either in practice or this past Sunday at Carolina. Washington designated No. 1 tight end Logan Thomas (hamstring) for return from injured reserve Wednesday, thus opening a 21-day window for him to get back on the active roster. Thomas' ability to practice seemingly puts him ahead of Seals-Jones on the health front, but if neither player gets the all-clear to play Monday versus the Seahawks, John Bates will be the primary tight end for Washington.
