What you need to know about Sunday's injuries

Cincinnati Bengals tight end Tyler Eifert's breakout season is on hiatus.

Eifert was forced from Sunday's season-opening 23-16 win versus the Baltimore Ravens after landing awkwardly on his arm in the first quarter. He was immediately sent to the locker room and did not return. NFL Media's Albert Breer reports, per a Bengals source, that the team believes the pass-catching tight end dislocated his elbow, likely sidelining him for an extended period.

Prior to the injury, Eifert was leading the Bengals' aerial attack with three catches for 37 yards in 12 minutes of action.

With Marvin Jones also injured, the Bengals will have to lean heavily on Mohamed Sanu and Giovani Bernard in the passing game.

Below is a running tally of all the essential injury news from Week 1's slate of games.
