Former Bills K Steve Christie made his retirement official Wednesday, more than three years after his last NFL game.

The agent for free-agent CB Nate Jones says the Cowboys are interested in re-signing him, but that several other teams are also in contention.

The Dolphins, Packers and Ravens are said to be interested in free agent WR Tab Perry.

Giants WR David Tyree has a book deal; his autobiography will come out in September.

Eagles CB Asante Samuel’s salary-cap figure for 2008 is $9.145 million; only QB Donovan McNabb has ever had a salary-cap figure that high for Philly.

The Patriots’ latest free-agent addition is former Vikings S Tank Williams.

Patriots WR Troy Brown hasn’t made a decision about whether he’ll try to return for a 16th season.

The Ravens don’t have enough cap room to sign starters in free agency, so they’re trying to add role players.

Lions coach Rod Marinelli likes to sign players he already knows, which is why several players have gone from Tampa Bay to Detroit.

The Bengals are expecting to receive three or four compensatory picks, which will be announced at the end of the month.

Said Browns coach Romeo Crennel of his first impressions of his defensive line, “It’s bigger, definitely.”

The Packers have made preliminary contact with free agent QB Mark Brunell about signing him to back up Aaron Rodgers.

The Steelers are considering signing free agent LB Tracy White to upgrade their special teams.

The Vikings have meetings scheduled with free agent defensive linemen Jevon Kearse and Ellis Wyms.

Kearse said after meeting with the Titans Wednesday, “This is my No.1 pick, my first choice. When I heard the Titans were interested I was like, ‘Let’s make something happen.’”

The Texans remain interested in free agent RB Warrick Dunn, in part because assistant head coach Alex Gibbs worked with Dunn in Atlanta.

New England is interested in signing restricted free agent Carolina LB Adam Seward; if the Panthers don’t match the Patriots’ offer, the Patriots will send the Panthers a fifth-round draft pick.

Jacksonville signed long snapper Brett Goode and gave a second-round tender offer to restricted free-agent S Gerald Sensabaugh.

Buccaneers P Josh Bidwell has written a book about surviving cancer.

Chiefs S Greg Wesley doesn’t understand why the team hasn’t released him.

The Raiders re-signed RT Cornell Green and restructured the contract of RB Dominic Rhodes.

Says 49ers GM Scot McCloughan of his expectations for 2008, “We’re going to be twice as good this year, in my opinion, on offense in keeping the ball in our hands and that’s going to make our defense better.”
