The Facts: The Bengals will be without Eifert (concussion) on Monday night against the Broncos, NFL Media's Rand Getlin reports.

Diehards Line: Eifert exited the Bengals' Week 14 loss to the Steelers after taking a hit from Steelers safety Mike Mitchell. He has since remained in concussion protocol. Getlin adds that the Bengals are not eager to rush Eifert back and though nothing is definitive yet, there is a chance he won't be back in action until the playoffs. Tyler Kroft will fill in as needed.
