Brown was a non-participant at Wednesday's practice due to a concussion, Nate Ulrich of the Akron Beacon Journal reports.
Brown played 29 offensive snaps and 21 special-teams snaps in Sunday's loss to the Patriots, but he likely picked up the head injury somewhere along the way. The 25-year-old has started the last five games but has only two catches for 27 yards. Brown will need to fully clear the five-step concussion protocol before returning to game action.
