The Carolina Panthers have acquired special teams star Colin Jones from the San Francisco 49ers for a seventh round pick.

Jones was a sixth round pick out of TCU in 2011.

Carolina showed interest in signing Jones last season when he was on the 49ers' practice squad.

Jones finished the season with eight tackles and seven "big plays" as graded by special teams coordinator Brad Seely.

The Miami Dolphins have taken calls from teams asking about Matt Moore.

Moore is currently backing up rookie Ryan Tannehill. As of Friday afternoon, injured veteran David Garrard was also still on Miami's roster.

The Dolphins will lack a proven quarterback behind Tannehill if they move Moore.

The Dallas Cowboys have acquired offensive lineman Ryan Cook from the Miami Dolphins, according to a source.

The Dolphins will receive a seventh round pick from Dallas.

The NFL and NFLPA have agreed to move the trade deadline after Week 8 of the regular season.

The two sides have also agreed to amend the rules concerning injured reserve.

The NFL has dropped its request for added padded practices. 

Also, players can practice right away when joining the team, abolishing the three-day rule for next year.

One NFL general manager told Jason La Confora of NFL.com that pushing the deadline back two weeks should increase trades because it is more clear who is beginning to plan for the next season at that point.

The Jacksonville Jaguars have no intention of trading away Maurice Jones-Drew.

General manager Gene Smith was asked about the possibility of trading away Jones-Drew on Wednesday.

Jones-Drew has said that he will not report to the Jaguars without a new contract. Jones-Drew has two seasons remaining on his current deal.

The Lions are thin in the backfield with just 12 days before the season begins.

Detroit GM Martin Mayhew has been calling around looking for help at running back.

Kevin Smith is No. 1 on Detroit's depth chart, but he injured his ankle this weekend against Oakland. Jahvid Best will begin the season on the PUP list and Mike Leshoure has been suspended for the first two games of the season for violating the NFL's substance abuse policy.

The Dolphins traded Vontae Davis to the Colts on Sunday, a move that left some members of the team unsure of where they are headed.

Karlos Dansby, who also questioned the decision to release Chad Johnson earlier this month, wasn't a fan of the move.

"I'll leave that up to you all," Dansby said. "I don't know what the situation was or what occurred to cause the trade.

"He's a great player, one of the best corners in the game. I'm not sure about the direction of the team. That's not my place. My place is to play hard and be the leader of men."

The Jets will trade Wayne Hunter to the Rams in exchange for Jason Smith.

Hunter was recently demoted by New York at right tackle in favor of Austin Howard.

Smith, the second overall pick by the Rams in 2009, has lost his starting job to Barry Richardson.

The Bills have agreed to send an undisclosed draft pick to the Seahawks for Tarvaris Jackson, according to NFL sources.

Buffalo is also trying to finalize a new contract with Jackson.

Jackson started 14 games for Seattle last season, but the Seahawks signed Matt Flynn as a free agent and drafted Russell Wilson in the third round.

The Bills have their starter in Ryan Fitzpatrick, while Vince Young, Tyler Thigpen and Brad Smith are still on the roster.

Colts owner Jim Irsay insists that the team is close to a significant trade and added that it could "go down this weekend."

There are rumors Indianapolis could be seeking an offensive tackle. Every potential trade target, including Maurice Jones-Drew, Mike Wallace, Mike Jenkins and Vontae Davis, has been denied by a source.
