The Cowboys will sign veteran kicker Kris Brown on Friday to the 53-man roster and give him a two-year deal, according to a source. The team will have to create a roster spot for Brown. David Buehler is expected to be the kicker in the season finale at Philadelphia, but it has been an up-and-down season for him.

The Bears have signed long snapper Patrick Mannelly to a two-year, $2.29 million extension. They also rewarded defensive tackle Matt Toeaina, who would have been a restricted free agent, with a three-year extension worth about $6 million. "(My wife and I) have been here for 13 years," said Mannelly, who received a $550,000 signing bonus and will be among the league's highest-paid at his position. "The Bears have been good to me. I don't know if I ever even want to leave Chicago in the future. It would have been hard to go out there and test the market knowing how much I enjoy playing for the Bears."

The Raiders have signed former United Football League punter Danny Baugher to their practice squad as insurance if Shane Lechler is unable to play this week. Lechler strained his hamstring during last Sunday's victory over the Broncos and briefly left the game. Baugher, who has never played in an NFL game, spent this season with Las Vegas of the UFL. He led the league with a 44.6-yard gross average and 36.7 net.

Graham, a defensive end, will miss the remainder of the season after tearing a knee ligament on Sunday night against the Cowboys. Burgess, who was cut by the Patriots before the season, was utilized by New England primarily as a defensive end in 2009. Burgess began his career with the Eagles when he was drafted in the third round of the 2001 draft by Philadelphia.

The Cardinals have signed quarterback Richard Bartel after placing rookie Max Hall on the injured reserve. Hall, an undrafted rookie out of BYU who started three games earlier this season, dislocated his left shoulder on Sunday against the Rams. Bartel was released by the Redskins in their final roster cut on Sept. 4.

The Jets are poised to re-sign wide receiver Laveranues Coles, a league source confirmed Saturday night. Coles was en route to New Jersey late Saturday and will sign Sunday morning, making him eligible for Monday night's battle with New England. He will replace safety Jim Leonhard, who was placed on the injured reserve.

The Raiders have signed quarterback J.T. O'Sullivan to be their third option behind Jason Campbell and Kyle Boller.
