There have been at least six teams working on finding background information on Adrian Peterson.

Peterson's future with the Minnesota Vikings is uncertain following his plea deal and suspension for child abuse.

Peterson played in just one game in 2014, rushing for 75 yards on 21 carries. Peterson now has over 2,000 carries for his career.

Duron Carter is close to an agreement to sign with the Indianapolis Colts.

Carter played for the Montreal Alouettes of the Canadian Football League last season.

The 6-foot-5 receiver was very productive in the CFL last season with 75 catches for 1,030 yards and seven touchdowns.

The Minnesota Vikings, Carolina Panthers, Washington Redskins, San Francisco 49ers and Cleveland Browns were also interested in Carter.

Carter is the son of Cris Carter.

The Oakland Raiders have signed Charles Woodson to an extension.

Woodson was scheduled to become a free agent this offseason.

Woodson re-joins the Raiders following a 2014 campaign in which he started all 16 games, leading the team with 160 tackles (105 solo) and four interceptions. 

Justin Forsett averaged 5.4 yards per carry in 2014, which led the NFL.

Forsett said the Baltimore Ravens have expressed interest in bringing him back.

"That is the plan, they gave me my shot, they trusted me and believed in me enough to give me that shot so I'd like to stay," Forsett told Around The NFL after Friday's Pro Bowl practice.

Forsett bounced around before finding a home with the Ravens.

"They expressed that they want me back. I want to be back, so we'll see what happens," he said.

Jimmy Haslam hasn't ruled out starting Johnny Manziel at quarterback for the Cleveland Browns in 2015, but he also said "every option is on the table."

The Browns also started Brian Hoyer and Connor Shaw at quarterback this season.

"We've got to get a quarterback and got to get it fixed," Haslam said Thursday night, via the Elyria Chronicle-Telegram. "What I would say to our fans is, we're going to continue to work really hard to find that quarterback who can make us a championship team."

The Browns used a first round pick on Manziel last year.

"Johnny has to show on and off the field he can be a professional," Haslam said. "He knows that. Everybody in the organization has told him that. It'll be up to Flip and (coach Mike Pettine) to decide whether he can be the kind of quarterback we need him to be. He knows what we expect of him on and off the field, and it's up to him to prove he can do that."

Peyton Manning plans on continuing his NFL playing career in 2015.

According to three trustworthy sources, Manning wants to return to the Broncos, but won't and can't make a final decision until he takes an annual physical examination mandated by his contract. 

The test results weren't known until March last season.

The Broncos have asked Manning to inform them of his plans by March 9, which is the day before teams must exercise their rights on veteran players under contract.

Manning is due $19 million next season.

The Dallas Cowboys would like to sign both Dez Bryant and DeMarco Murray to long-term deals, but Jerry Jones acknowledged it will be difficult.

"It's going to be a challenge," Jones said. "Is it financially reasonable? No. Is it possible? Yes.

"But if you just looked at it from dollars and cents, it probably doesn't look reasonable. You have to figure out how you get there, but at the end of the day you realize it's going to be costly to have both of those players."

Bryant appears to be the higher priority.

If the Cowboys can't reach a long-term agreement with Bryant, Jones has said they will use the franchise tag on him, which will pay the receiver about $12.5 million in 2015.

Jones said he's not interested in restructuring a contract like quarterback Tony Romo's deal, which will count nearly $27 million for a luxury item.

The Dallas Cowboys had a four-year deal worth slightly more than $16 million on the table for DeMarco Murray.

Murray had a career-high 497 touches in 2014.

Murray would certainly receive more than $4 million per season on the open market.

The New England Patriots have signed starting safety Patrick Chung to a three-year contract extension through 2017, a deal that could be worth up to $8.2 million and includes $3.4 million in guarantees, according to a source.

Chung was a second round pick by the Patriots in 2009 and spent one season with the Philadelphia Eagles in 2013.

As part of the extension, Chung received a $2.4 million signing bonus. He will earn base salaries of $1 million in 2015, $1.4 million in 2016 and $1.8 million in 2017. 

Martin Mayhew said the Detroit Lions are open to all options with defensive tackle Ndamukong Suh, including potentially using the franchise or transition tags on the free agent-to-be.

"He certainly is a big priority for us and he's an important part of our football team the past five years and I think the world of him," Mayhew said.

Mayhew said he spoke with Suh on Monday and he is "looking forward to working with him" to try and get a deal done. Mayhew said the team would prefer to sign a long-term deal with Suh, who would be one of the most sought-after free agents in 2015 if he reaches March without a deal.
