Pittsburgh Steelers running back Le’Veon Bell has been officially ruled out for Saturday night’s wild-card game against the Baltimore Ravens because of a hyperextended right knee.

The team announced Friday that Bell won’t play after he suffered the injury last week and hasn’t been able to practice this week. Bell left the Steelers’ 27-17 win over the Cincinnati Bengals week after taking a helmet shot on his knee. He is the AFC’s rushing champ with 1,361 yards on the ground and also caught 83 passes for 854 yards.

The Steelers signed fourth-year veteran Ben Tate as running back insurance Tuesday. Rookie Josh Harris likely will start against the Ravens. Dri Archer can play a role out of the backfield on passing downs and Tate also could see action.

Safety Troy Polamalu (knee) was listed as probable for the playoff game. He has missed the previous two games and four of the last seven due to numerous injuries.

—Cincinnati Bengals wide receiver A.J. Green, who did not practice Friday, is listed as doubtful for Sunday’s wild-card game against the Indianapolis Colts.

Green, who was scheduled to visit an independent neuropsychologist on Friday, was seen at practice in sweats. The Bengals’ biggest receiving threat remains under the league-mandated concussion protocol. Green suffered the injury in the fourth quarter of a 27-17 loss at Pittsburgh last Sunday night. Green was hurt on a hit delivered by Steelers cornerback cornerback Antwon Blake and moments later by safety Mike Mitchell.

Meanwhile, the Bengals officially ruled out wide receivers James Wright (knee) and Dane Sanzenbacher (concussion) for Sunday’s game. Sanzenbacher was placed on injured reserve Wednesday and replaced on the playoff roster by wide receiver Cobi Hamilton.

—The Colts will be without right guard Hugh Thornton on Sunday for their wild-card game against the Bengals because of a right shoulder injury.

Injuries kept Thornton from playing in four of the Colts’ final five regular-season games. He left the regular-season finale against the Tennessee Titans with a shoulder injury. Also missing will be right tackle Gosder Cherilus, who was placed on injured reserve Wednesday.

—Houston Texans defensive lineman J.J. Watt and New England Patriots tight end Rob Gronkowski were unanimous picks on the Associated Press All-Pro team announced Friday.

Watt made it onto all 50 ballots, with 45 as a defensive end and five as a defensive tackle. Gronkowski was honored after finishing the regular season with 82 receptions for 1,124 yards and 12 touchdowns.

The Dallas Cowboys, who won the NFC East title, placed an NFL-best four players on the team: rookie guard Zack Martin, league rushing leader DeMarco Murray, offensive tackle Tyron Smith and wide receiver Dez Bryant. The Seattle Seahawks and Pittsburgh Steelers were next with three each. AFC players landed 16 of the 27 spots.

—The Tennessee Titans denied the Tampa Bay Buccaneers’ request to interview tight ends coach Mike Mularkey for their offensive coordinator position, NFL Network reported Friday.

Tennessee head coach Ken Whisenhunt valued Mularkey enough to want to keep him with the Titans, who finished 2-14 in Whisenhunt’s first year with the team. Mularkey, who has been an offensive coordinator in Pittsburgh, Miami and Atlanta, joined Tennessee this season after not coaching in 2013. His last job as an offensive coordinator was with the Falcons from 2008 to 2011.

—The Buffalo Bills have requested permission to interview Denver Broncos offensive coordinator Adam Gase for their head coach position, according to multiple reports.

Gase, 36, was expected to interview Friday with the Atlanta Falcons and San Francisco 49ers for their openings, then meet with the Chicago Bears on Saturday.

Gase is the first potential candidate to emerge for the Bills after former coach Doug Marrone opted out of his contract Wednesday.

—The Kansas City Chiefs granted permission for the Chicago Bears to interview personnel director Chris Ballard for the vacant general manager position, according to reports Friday.

Ian Rapoport of NFL Media reported that Ballard will be interviewed in Chicago on either Friday or Saturday. Ballard was linked to the Bears opening almost immediately after Phil Emery was fired as general manager on Monday. Emery was 23-25 in three seasons with the Bears, firing Lovie Smith after a 10-6 season in 2012 and replacing him with first-time NFL head coach Marc Trestman, who also was let go Monday.

Ballard spent 12 years with the Bears before jumping to Kansas City before the 2013 season.

—The Green Bay Packers promoted Eliot Wolf to director of player personnel on Friday.

Wolf, 33, has been with the Packers for 11 years, including the last three years as director of pro personnel. Wolf is the son of Ron Wolf, the former longtime Packers general manager who is a finalist this year for the Pro Football Hall of Fame.

Ron Wolf, who retired as a Packers front-office executive in 2001, has joined Charley Casserly as consultants to New York Jets owner Woody Johnson in the search process after coach Rex Ryan and general manager John Idzik were fired Monday.

—Packers quarterback Aaron Rodgers did not practice on Friday and is not expected to be back on the field until next Thursday.

The Packers, who won the NFC North title and secured a playoff bye this weekend with the No. 2 seed, returned to practice after their 30-20 win over the Detroit Lions last Sunday.

Rodgers, named to the AP All-Pro team on Friday, said the calf injury is slowly improving. He was injured during Sunday’s game against the Lions.

Green Bay wide receiver Jordy Nelson also didn’t practice because he was attending to a personal matter, coach Mike McCarthy said.

—The casualties of the New Orleans Saints’ disappointing 2014 season include three assistant coaches who have been dismissed, according to reports Friday. Longtime tight ends coach Terry Malone, wide receivers coach Henry Ellard and assistant secondary coach Andre Curtis will not return next season. Defensive coordinator Rob Ryan’s status remains unclear.

The Saints finished with a 7-9 record and a defense that was ranked 31st in the NFL in yards allowed.

Malone was a member of Payton’s first staff with the Saints, starting in 2006. Ellard had a long career in the NFL as a receiver. He came to the Saints in 2012, as did Curtis.

—The Tampa Bay Buccaneers signed seven players to future contracts on Friday.

Free agent players signing for the 2015 season are: defensive back Shelton Johnson, wide receiver Chandler Jones, quarterback Seth Lobato, defensive tackle Matt Masifilo, tackle Matt Patchan, cornerback Jocquel Skinner and guard Jeremiah Warren.
