The addition of cornerbacks Darrelle Revis and Brandon Browner gives the New England Patriots' mediocre secondary an improved look.

After allowing the 15th most yards passing in the NFL — and 400 yards to Peyton Manning in a 26-16 loss in the AFC championship game last season — the Patriots moved with uncharacteristic speed to add outstanding veteran free agents.

The team announced on Saturday the signing of Browner, one day after the suspended former Seattle Seahawks player said on his Twitter account that he has agreed to a contract with the Patriots.

The Patriots have not announced the signing of Revis, but John Geiger, his business manager, said on Twitter on Thursday that the three-time All-Pro had agreed to terms with the team.

Neither the team nor the players released details of the deals, although Browner's reportedly was worth $17 million US over three years and Revis' reportedly was worth $12 million for one year.

Two of last year's starters in the secondary are gone. Cornerback Aqib Talib, a big, talented defender, left for the Denver Broncos, while safety Steve Gregory was released.

Packers get jolt with Peppers signing

The Green Bay Packers defence has gotten a big jolt from a big name: Eight-time Pro Bowl defensive end Julius Peppers.

The ex-Carolina Panthers and Chicago Bears defensive end signed a three-year deal with the Packers on Saturday morning, bringing one of the NFL's best pass-rushers to a team that has historically avoided major free-agent splashes.

The move was first reported by ESPN. Peppers' agent, Carl Carey, posted photos to his Twitter account of Peppers signing the deal and standing on the still-frozen tundra of Lambeau Field before the team announced it officially later in the day.

The 34-year-old Peppers was released Tuesday by the Bears in a cost-cutting move. Peppers would have counted $18.183 million against Chicago's salary cap this season and had a base salary of $13 million.

Zach Miller restructures deal with Seahawks

Zach Miller will stay with the Seattle Seahawks after the tight end agreed to restructure his contract in an effort to free up salary cap room for the Super Bowl champions.

The team confirmed the Miller's restructured deal on Saturday, which was first reported by 710 ESPN radio in Seattle. Terms of Miller's new deal were not immediately available, but it keeps an important piece of the Seahawks offence in Seattle after two starters — wide receiver Golden Tate and right tackle Breno Giacomini — left earlier this week in free agency.

Miller has become vital as both a pass receiver and blocker for the Seahawks offence. Miller had 33 receptions and five touchdowns in the 2013 regular season, but his ability to block on the edge and help the run game led by Marshawn Lynch has proven just as important.

Miller was due to make $4.8 million in base salary in 2014 before restructuring.

Panthers agree to deal with Roman Harper: report

A person familiar with the situation says the Carolina Panthers have agreed to terms on a two-year contract with Saints free agent safety Roman Harper.

The person spoke on condition of anonymity to The Associated Press on Saturday because the deal has not been announced.

Financial terms were not available.

The 31-year-old Harper has been a mainstay at strong safety in New Orleans for the past eight seasons and went to the Pro Bowl in 2009 and 2010. He only played in five games last season due to injuries.

Harper is expected to fill the void left by Mike Mitchell, who signed earlier this week with the Pittsburgh Steelers.

The 6-foot-1, 200-pound Harper has 17 career sacks, the most by any defensive back since 2006. He's also forced 13 fumbles.

Ben Tate inks 2-year deal with Browns

Ben Tate was on the Browns' radar for months. He's now on their roster.

Tate signed a two-year, $7 million free agent deal on Saturday with Cleveland, which has been desperate to find a quality every-down running back since trading Trent Richardson to Indianapolis early last season.

Tate, who spent the past four years with Houston, fills the void and the 25-year-old seems excited to begin a new chapter of his career with the Browns.

"LET'S DO THIS CLEVELAND!! (hashtag) DawgPound," Tate posted on his Twitter account along with a photo of him wearing a Browns ball cap.
