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.
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.
New York kick returner-running back Joe McKnight injured his ribs in the third quarter and didn't return.
Lions rookie receiver Ryan Broyles appeared to injure his right knee midway through the first quarter against Indianapolis. Broyles tore a ligament while he was a senior at Oklahoma, but that was in his left knee.
Colts offensive lineman Joe Reitz left in the first quarter with a suspected concussion.
Chiefs cornerback Brandon Flowers and safety Abe Elam were sidelined against Carolina. Elam left with a left leg injury and Flowers hobbled to the sideline with a hamstring injury after making a tackle late in the first quarter.
Panthers linebacker James Anderson left with an eye injury.
Already down starter Maurice Jones-Drew (left foot) and backup Jalen Parmele (groin), the Jaguars lost running back Rashad Jennings, who sustained a concussion in the second quarter against Buffalo. Then their leading receiver, Cecil Shorts III, sustained a concussion in the fourth quarter.
The list of injuries is growing for the Bills, too.
Leading receiver Stevie Johnson did not return after hurting his left hamstring in the third quarter. Center Eric Wood hurt his left knee, and right tackle Chris Hairston couldn't finish after hurting his right ankle. Cornerback and return specialist Leodis McKelvin also couldn't finish because of a nagging back injury.
Broncos linebacker Wesley Woodyard left against Tampa Bay with an ankle injury.
