A revolving door at quarterback isn't the Minnesota Vikings' only issue.
The secondary is beat up as well. Vikings defensive backs Jamarca Sanford and Chris Cook will miss this week's game because of injuries. Safety Harrison Smith is on injured reserve. All three are normal starters in the Vikings secondary.
Even worse, the opponent this week is the Cowboys, who are eighth in the NFL at 261.2 passing yards per game. Dallas quarterback Tony Romo should have a big day against a secondary that doesn't have much available manpower to compete this week.
Here's the rest of the week's injury report:
Kansas City Chiefs at Buffalo Bills: The most important injury is to Bills quarterback Thad Lewis, who is doubtful with a rib injury. The indication is that Jeff Tuel will start for him. Quarterback EJ Manuel continues to be out with a knee injury.
The Chiefs are fairly healthy headed into the game.
Atlanta Falcons at Carolina Panthers: Receiver Roddy White is questionable, and will be a game-time decision. One has to think that White, who tried valiantly to play through an ankle injury earlier this year, will lobby the coaches and trainers to let him play. He has missed two games and the Falcons could use him back. They'll wait on left tackle Sam Baker (knee), defensive end Osi Umenyiora (knee) and safety William Moore (hip), who are also questionable.
The Panthers are remarkably healthy. Little used receiver Marvin McNutt is probable, and that's the extent of the injury list.
Minnesota Vikings at Dallas Cowboys: Dallas will likely be without defensive end DeMarcus Ware and receiver Miles Austin, who are doubtful. Running back DeMarco Murray is listed as probable, and should play for the first time since he injured his knee Oct. 13.
New Orleans Saints at New York Jets: Receiver Marques Colston missed practice Friday, and is a game-time decision with a knee injury. He has been a surprising non-factor most of the season anyway. The Saints have a long list of questionable players but only Colston and defensive back Malcolm Jenkins missed Friday's practice.
The Jets will be without receiver Santonio Holmes again. He was ruled out. The rest of the Jets' key players participated in practice Friday.
Tennessee Titans at St. Louis Rams: Linebacker Moise Fokou was ruled out, but replacement Colin McCarthy might be the better player anyway. Tackle David Stewart didn't practice Friday with a shoulder injury and is questionable.
Standout defensive end Robert Quinn didn't practice Thursday or Friday because of illness and is listed as questionable, it would obviously be a huge blow if he can't play. Running back Zac Stacy was downgraded from full practice on Thursday to limited on Friday with a foot injury he suffered against Seattle, and running back Daryl Richardson is also questionable with a foot injury. Richardson didn't practice Friday and probably is in greater danger than Stacy of missing Sunday's game.
San Diego Chargers at Washington Redskins: The only significant injury for either team is that Chargers linebacker Donald Butler is doubtful with a groin injury.
Philadelphia Eagles at Oakland Raiders: Quarterback Michael Vick is out and Nick Foles will start for the Eagles. The other issue worth watching is oft-injured safety Patrick Chung, who is questionable with a shoulder problem.
Raiders safety Tyvon Branch continues to remain out with an ankle injury. Two offensive linemen, Andre Gurode and Tony Pashos, are out, although rookie tackle Menelik Watson returned to practice this week and is questionable.
Tampa Bay Buccaneers at Seattle Seahawks: Running back Marshawn Lynch, who sat out Wednesday and Thursday, returned to a full practice Friday and is probable. Seattle remains beat up on the offensive line, with both tackles out, and receiver Sidney Rice is done for the season with a torn ACL.
Guard Carl Nicks and running back Doug Martin are out this week, but there are no other major injury issues for Tampa Bay.
Baltimore Ravens at Cleveland Browns: Ravens starting guard Kelechi Osemele, who is out, is the only significant injury for either side.
Pittsburgh Steelers at New England Patriots: New England cornerback Aqib Talib is questionable with a hip injury, but with the bye next week the Patriots might play it safe and keep him out. Defensive tackle Tommy Kelly is out but the rest of the team is questionable or better, including banged up tight end Rob Gronkowski, who is probable.
Guard David DeCastro is the only major contributor out for the Steelers.
Indianapolis Colts at Houston Texans: The most significant injury is Colts cornerback Greg Toler, who is out. Both teams are relatively healthy other than that. Texans running back Arian Foster is listed as questionable, but practiced in full on Friday.
Chicago Bears at Green Bay Packers: The injury-plagued Packers got some good news when receiver James Jones was able to go through a limited practice on Friday. He could help the Packers, who are without receiver Randall Cobb and tight end Jermichael Finley. Outside linebacker Clay Matthews is out too.
The Bears will be without quarterback Jay Cutler and linebacker Lance Briggs but appear healthy otherwise.
