The Chargers signed kicker Nick Novak on Friday.

Nate Kaeding has an apparent groin injury and is listed questionable.

Kaeding, who'd gone 7-for-7 on field goals, hadn't been on an injury report this season.

"He was sore when he started kicking today, and wasn’t able to continue," coach Norv Turner said.

Malcom Floyd signed a three-year contract extension with the San Diego Chargers that will carry through the 2015 season.

Floyd signed a two-year deal with the team shortly after the NFL Lockout ended last season and has been with the team since 2004.

Korey Hall has been added to the active roster of the Arizona Cardinals.

Hall spent four seasons with the Packers as a fullback and special teams player after being drafted out of Boise State.

Hall was in camp with the Saints before being cut.

Andre Carter has signed with the Oakland Raiders.

Carter was a Pro Bowler in 2011 with the New England Patriots.

The Raiders have only recorded three sacks over their first three games.

Deion Branch has agreed to a deal to re-sign with the New England Patriots, according to a source.

The Patriots released Branch shortly before the season.

New England needed help at receiver following the injury to Aaron Hernandez.

The New England Patriots have agreed to a one-year deal with Kellen Winslow Jr.

The Patriots will be without Aaron Hernandez indefinitely after his ankle injury in Week 2.

Winslow was released by the Seahawks before the beginning of the regular season.

The Oakland Raiders made four roster moves ahead of Sunday's Week 2 game against the Dolphins.

The Raiders promoted both cornerback Coye Francies and long-snapper Nick Guess from the team’s practice squad, placed wide receiver Jacoby Ford on season-ending reserve/injured, and placed cornerback Ron Bartell on the NFL’s new reserve/injured list that allows him to return later this year.

The Chicago Bears re-signed Kahlil Bell on Saturday to add depth at running back with Matt Forte nursing a sprained ankle.

''I'm taking my talents back to Chicago. So happy to be back,'' Bell tweeted Saturday. "Never wanted to leave."

Bell played with the Bears the past four seasons, including three starts in 2011. 

The Dallas Cowboys and defensive end Sean Lissemore agreed to a three-year extension with $3.1 million guaranteed and a $2 million signing bonus.

“That’s a steal for them,” one agent not involved in the deal said. 

Lissemore was a seventh round pick in 2010.

"The Cowboys like him and Sean likes being there," Lissemore's agent Wes Bridges said. "Quite frankly, Sean had a decision to make and see if he wanted to wait it out and go to next year, but he didn't want it to be a distraction and wanted to just play ball. He wanted to get a deal done and get it done this year." 

The Cowboys see Lissemore as a future starter.

The Cowboys are known for giving out big extensions, but the team has built a defensive line with good depth in an affordable way.

Andre Carter worked out for the Arizona Cardinals on Tuesday.

Carter was a Pro Bowl selection last season while with the Patriots.

Carter had 10 sacks with New England in 2011.
