The Cincinnati Bengals placed wide receiver John Ross on injured reserve Wednesday with a shoulder injury he suffered Monday night.
The Bengals said Ross injury was specifically to the sternoclavicular joint in his right shoulder.
It is unclear if Ross has a chance to return this season. By rule he must be on injured reserve for eight weeks before the Bengals would be able to designate him to return.
The third-year receiver was knocked out of Cincinnati's 27-3 loss to Pittsburgh on Monday night after he was slammed to the turf in the fourth quarter, with his right shoulder sustaining most of the impact.
