Seals-Jones (illness) was listed as a non-participant on Wednesday's estimated injury report, Nate Ulrich of the Akron Beacon Journal reports.
The Browns didn't actually practice, but if they had, Seals-Jones was the only member of the roster that would have sat out. However, a return to the field Thursday or Friday could be all Seals-Jones needs to get the green light to play Sunday against Cincinnati.
