Seals-Jones (illness) wasn't present on the field for Thursday's practice, Nate Ulrich of the Akron Beacon Journal reports.
The Browns listed Seals-Jones as a non-participant on their initial practice report released Wednesday, and the tight end looks poised to maintain that listing for a second straight day. If Seals-Jones is able to return to practice Friday and put in a full workout, he'll stand a good chance at avoiding a designation heading into Sunday's season finale versus the Bengals.
