Seals-Jones didn't practice Wednesday due to a shoulder injury, Scott Bordow of The Athletic reports.
It's been a tough go for Seals-Jones over the last week. After enduring a bout with food poisoning, he gained clearance to play in Sunday's loss to the Rams, only to last five offensive snaps before a stinger ended his day. Seals-Jones has a pair of practices remaining to prove his health, but an absence in the season finale against Seattle would allow Jermaine Gresham and John Phillips to pick up snaps at tight end.
