The St. Louis Rams won't have one of their top pass rushers against Joe Flacco and the Ravens.
On Saturday, the team downgraded defensive end Robert Quinn from questionable to out for Sunday's game at M&T Bank Stadium. Quinn, who is second on the team with five sacks, has been dealing with back and hip injuries.
Quinn played on a limited basis in the Rams' loss to the Chicago Bears last week after missing the previous week's game. When healthy, the two-time Pro Bowl selection is considered one of the league's top pass rushers. He had 19 sacks in 2013 and 10 1/2 last year.
Chris Long, the Rams' other starting defensive end, is questionable for Sunday's game with a knee injury that has sidelined him for four consecutive contests.
While Ravens rookie tight end Nick Boyle is not expected to play Sunday because of a foot injury, the team's biggest injury question is starting left guard Kelechi Osemele. He missed practice Wednesday and Friday of this week and is considered questionable for Sunday.
The Ravens already need their top reserve guard, John Urschel, to start at center with Jeremy Zuttah (torn pectoral) out for the season. If Osemele was out, they'd likely start Ryan Jensen at left guard.
The Ravens have until 4 p.m. today to activate defensive end Brent Urban to the 53-man roster, but they are likely to hold off another week before doing so. The Ravens are comfortable with their depth at defensive end and feel that Urban, who is on the injured reserve-designated to return list after tearing his biceps in training camp, would benefit from another week of practice.
