After weeks of lopping defenders from their roster, the Buffalo Bills have reached the welcome-back stage.

The Bills have reached an agreement with veteran Bryan Scott, who would have become an unrestricted free agent next Tuesday.

The hybrid linebacker/defensive back revealed on his Twitter account Wednesday afternoon he’d signed a contract extension. Scott confirmed to The Buffalo News the contract is for one year. Financial terms aren’t known yet.

“Dedicated to make the city of Buffalo proud and give them something great to cheer for,” Scott tweeted.

The Bills had not confirmed the Scott signing as of Wednesday night, but they did announce they’d exercised their exclusive-rights qualifying offer to tight end Dorin Dickerson.

As a player with fewer than three accrued NFL seasons, Dickerson must accept the offer or not play in the NFL.

In 11 games for the Bills last year, Dickerson had nine catches for 117 yards and one end-around run for minus-8 yards. He lost one fumble on his 10 touches.

Scott, entering his 11th season, is Buffalo’s most experienced position player on defense under contract. Kicker Rian Lindell is heading into his 14th season.

The Bills have shed several notable veterans from their defense in the past month. They released linebacker Nick Barnett and safety George Wilson, last year’s top two tacklers, and cornerback Terrence McGee.

Veteran defensive ends Chris Kelsay and Shawne Merriman announced their retirements.

Scott perhaps was Buffalo’s best big-play defender with six takeaways, including an interception return for the team’s lone defensive touchdown.

He was fifth on the Bills with 64 tackles last season. He tied for the team lead with two forced fumbles. He was second to safety Jairus Byrd in interceptions with four and second to cornerback Stephon Gilmore in pass breakups with eight.

Scott is familiar with new head coach Doug Marrone and new defensive coordinator Mike Pettine.

Scott spent 2006 with the New Orleans Saints, where Marrone was offensive coordinator under Sean Payton.

In high school, Scott starred for Central Bucks East. Pettine’s father was the legendary head coach at Central Bucks West, and Pettine coached at North Penn. All of those schools belong to the Suburban One League in the Philadelphia area.
