Undermanned Chicago was hit with more injuries Sunday in a loss to Seattle, including to star linebacker Brian Urlacher.
Urlacher injured a hamstring in the 23-17 defeat. Cornerback Tim Jennings (shoulder) also was hurt on the Seahawks' winning drive, after receiver Earl Bennett (concussion) and safety Chris Conte (illness) left earlier in the game.
The Bears had already ruled out return specialist Devin Hester (concussion) and guard Chris Spencer (knee) after they were injured against Minnesota. Throw in the torn ACL guard Lance Louis suffered against the Vikings, and the Bears were a short-handed bunch.
Dolphins left tackle Jake Long hurt his left triceps against New England. Long, the top overall pick in the 2008 draft, stood on the sideline in the second quarter with a bag of ice on his arm and didn't return. X-rays were taken, but the team didn't release the results.
Last year he went on injured reserve before the final game because of a torn right biceps.
49ers wide receiver Mario Manningham (shoulder) did not return after getting hurt in the fourth quarter at St. Louis. Coach Jim Harbaugh said the team "won't know right away" about the severity of the injury.
Already injury-depleted, Green Bay lost receiver Jordy Nelson (hamstring) and offensive lineman T.J. Lang (ankle). Lang started the first nine games at left guard before moving over to right tackle after Bryan Bulaga suffered a season-ending hip injury.
The Titans lost right tackle David Stewart, who broke his right leg on the opening series against the Texans. Stewart was blocking on a 26-yard running play by Chris Johnson when Texans linebacker Barrett Ruud rolled into his right leg. Trainers put an air cast on Stewart's lower right leg, while a cart quickly came out to pick him up.
Left guard Steve Hutchinson injured his right knee, returned briefly in the third quarter when left tackle Michael Roos got hurt, then limped off the field before returning on the next series. Titans receiver Damian Williams hurt a hamstring missing a pass as he went out of bounds and collided with a security guard.
Houston cornerback Brice McCain, starting with Johnathan Joseph out, hurt his left foot in the first half. Tight end Garrett Graham suffered a head injury.
Jets tight end Dustin Keller left against the Cardinals with an injured left ankle. Keller was hurt late in the opening half, hopping off the field and being checked out on the sideline by trainers before walking to the locker room.
