The Green Bay Packers' injury-riddled, struggling secondary won't be getting one of its veterans back anytime soon.
NFL Network's Mike Garafolo reported Tuesday that corner Sam Shields is headed to injured reserve due to a concussion.
The team later confirmed the move.
Shields missed the past four games while dealing with the symptoms. Garafolo reports that Shields' symptoms have not subsided as the team originally anticipated.
The corner posted a message on his Instagram account stating that he hopes to return this season.
The team could activate Shields off IR after eight weeks. The earliest he could return is Dec. 15 at Chicago.
Shields has suffered five concussions in his career and doctors want to ensure the 28-year-old is fully recovered from the latest head injury before he steps on the field.
