NFL news: Adrian Peterson likely out Week 15, won't need surgery

Larry French

Adrian Peterson initially expected to play in Week 15, but that no longer appears to be the case. That and more of the latest NFL headlines.

Adrian Peterson was able to avoid a serious foot injury, but after undergoing additional tests it doesn't appear he will be able to return to the field as soon as he originally expected. Following a CT scan Monday, the Minnesota Vikings determined that Peterson will need to spend time in a walking boot and is unlikely to play this week against the Philadelphia Eagles.

Peterson was carted off the field Sunday. An X-ray and MRI came back negative, which led to Peterson saying he expected to return to the field in Week 15. Instead, he will spend time in a walking boot and before needing to prove he can run full speed to return. With just three games remaining in the regular season and the Vikings out of playoff contention, Minnesota may choose to hold Peterson out the rest of the year instead of rushing him back and risking further injury.

The good news for Peterson and the Vikings is the CT scan didn't reveal a fracture or any structural damage, and the injury will not require surgery.

Mike Munchak not concerned about job security

The Tennessee Titans are now 5-8 and likely on the outside of the AFC playoff race. Head coach Mike Munchak has been rumored to be on the coaching hot seat, but he told reporters he isn't focused on his job status.

"We have three games to go," Munchak said. "We have a lot of football to play, so that is not a concern right now."

The Titans were active during the offseason, spending more than $100 million on free agent contracts. They started the season well, opening with a 3-1 record, but have struggled since with several close losses. With just one year remaining on his contract, Munchak may need a strong finish to remain head coach.

Eagles-Bears flexed to primetime in Week 16

When the Philadelphia Eagles and Chicago Bears play in Week 16, they will do so in primetime. NBC decided to flex the game to Sunday Night Football. The New England Patriots and Baltimore Ravens were originally scheduled to play in primetime, but that game is now scheduled to kickoff at 4:25 p.m. ET.

Both games will have serious playoff implications, but the Eagles and Bears could be playing for division titles in Week 16. The Patriots are secure at the top of the AFC East and will likely only be playing for seeding in Week 16. The Ravens are currently in the wild card race. Flexing the Bears and Eagles into primetime, however, will give the NFL a better late-afternoon schedule and give CBS a marquee matchup.

Cardinals will be aggressive attempting to re-sign players

Arizona signed a number of veterans to one-year contracts last offseason and several have gone on to play key roles for the Arizona Cardinals. Now, Arizona will attempt to re-sign several of those players before they hit free agency. Karlos Dansby, Eric Winston, Yeremiah Bell and Rashard Mendenhall are among the players currently on one-year deals.

Dansby has played especially well after being released by Miami during the offseason. The 32-year-old leads the team with 105 tackles. General manager Steve Keim said the Cardinals will continue to pursue extensions with several players, but said the market may dictate the outcome:

"We are going to aggressively approach several of these guys. I have already to some degree. We are going to try and put something in place to try to keep some continuity here, particularly for the guys who are playing well. But in some regard, the fans and media are going to have to understand, sometimes the market dictates what happens. The agents and the players sometimes want to see what's out there."

Sean Lee has no structural damage

Sean Lee's return didn't last long. The Dallas Cowboys linebacker left the game on Monday with a neck injury. While Lee has stiffness and soreness in his neck, he did not suffer any structural damage and should be able to play this week.

Injuries have plagued Lee throughout his career. He was limited to six games last season and missed two games earlier this season with a hamstring injury. When healthy, he's proven to be one of the better middle linebackers in the NFL.
