Peterman to start at QB for Bills

BUFFALO, N.Y. — Nathan Peterman will start at quarterback for the Buffalo Bills on Sunday against the Chicago Bears after Derek Anderson was ruled out with a concussion.

The Bills (2-6) said Saturday that Anderson and rookie linebacker Tremaine Edmunds have not cleared concussion protocol.

Rookie quarterback Josh Allen has a sprained elbow) and already has been ruled out for a third straight game. Anderson was hurt in the final minutes of a 25-6 loss to New England on Monday night.

Buffalo signed journeyman Matt Barkley on Wednesday to back up Peterman.

Cardinals release Bradford

The Arizona Cardinals have released quarterback Sam Bradford.

Bradford, whose eight NFL seasons have been plagued by injuries, signed a one-year, $20 million contract — with $15 million guaranteed — in the offseason. He started the first three games before being replaced by rookie Josh Rosen.

Bradford had been inactive for every game since.

WR Allison out for Packers against Pats

Packers receiver Geronimo Allison will miss Green Bay’s game against the New England Patriots on Sunday night with multiple injuries.

The Packers downgraded Allison from doubtful on Saturday, when the team had a light practice. Allison did not travel to New England.

He was a key contributor in the passing game before missing two weeks with a hamstring injury. He had one catch for 14 yards in returning against the Rams last week, then hurt his groin this week in practice.

Bears place Long on IR

The Chicago Bears placed right guard Kyle Long on injured reserve because of a tendon injury in his right foot.

The move means the NFC North-leading Bears (4-3) will be without Long for at least eight weeks.

The three-time Pro Bowl lineman was injured in the closing minutes of the Bears’ 24-10 victory over the New York Jets last weekend. Tight end Dion Sims rolled into Long while the two were blocking for Jordan Howard on a run.

Chicago visits Buffalo on Sunday. Tight end Ben Braunecker (concussion) and defensive tackle Bilal Nichols (knee) did not travel with the team, and star linebacker Khalil Mack (ankle) and receiver Allen Robinson (groin) are questionable.

AP source: Raiders to release leading pass rusher Irvin

The Oakland Raiders are planning to cut Bruce Irvin after the team’s leading pass rusher had his playing time reduced significantly in recent weeks.

A person familiar with the decision said Saturday the move should be official next week. The person spoke on condition of anonymity because the team hadn’t announced the transaction. The Athletic first reported the decision.

Irvin played just nine snaps in a 34-3 loss to the San Francisco 49ers on Thursday night. He will be subject to waivers and will be owed about $3.8 million for the rest of the season if he isn’t claimed.

Oakland came into the year banking on Irvin and Khalil Mack to serve as bookend pass rushers anchoring the defense. Mack was traded a week before the season to Chicago for a package of draft picks following a lengthy contract holdout, and now Irvin is on his way out too.

The Raiders (1-7) rank last in the NFL with just seven sacks.
