ASHBURN, Va. — Washington Redskins coach Jay Gruden said “there’s a lot of concern” over whether linebacker Perry Riley and safety Ryan Clark, both former LSU standouts, will play in Sunday’s game against the Arizona Cardinals.

Neither player has practiced this week. Both were listed as questionable on the injury report Friday.

Gruden is more pessimistic about Riley’s chances. Riley sprained the MCL in his left knee in Monday night’s loss to Seattle. Clark is nursing two sprained ankles from the same game.

Gruden said tight end Jordan Reed is “making great progress” from a pulled left hamstring and might play Sunday. Reed was injured in the season opener.

Reed was limited in practice Friday and is listed as questionable.

Patriots

BRADY QUESTIONABLE WITH ANKLE INJURY: In Foxborough, Massachusetts, Tom Brady is listed as questionable for Sunday’s New England Patriots game at Buffalo because of ankle injury.

The quarterback, who wasn’t on the club’s injury report on Wednesday or Thursday, was listed as having limited participation in Friday’s workout. But the injury doesn’t appear serious and he is expected to play.

Brady, who hasn’t missed a game since suffering a season-ending knee injury in the 2008 opening game, had his best game of the season in last Sunday night’s rout of the Cincinnati Bengals, throwing for a season-high 292 yards and two touchdowns.

Brady is no stranger to the injury report. There was a time where he was listed as “probable” on the weekly report because of a shoulder problem.

Bears

BRIGGS OUT FOR FALCONS GAME: In Lake Forest, Illinois, seven-time Pro Bowl linebacker Lance Briggs of the Chicago Bears has been ruled out for Sunday’s game in Atlanta due to a rib injury.

Coach Marc Trestman said Friday there was no indication Briggs had broken ribs but was too sore. Briggs hasn’t practiced all week.

Briggs’ replacement at weakside linebacker would be either Jonathan Bostic, second-year linebacker Khaseem Greene or rookie Christian Jones. Bostic was questionable for Sunday’s game with a back injury and also hasn’t practiced this week.

Starting safety Chris Conte and defensive tackle Jeremiah Ratliff are both probable for the game after suffering concussions.

Starting offensive tackle Jermon Bushrod (knee/ankle) and linebacker Shea McClellin (hand) have been ruled out.

Fines

VIKINGS’ EXUM FINED $22K FOR ILLEGAL BLOCK: In New York, Minnesota Vikings safety Antone Exum was fined $22,050 by the NFL for an illegal blindside block against the Green Bay Packers last week.

Exum was penalized for hitting the Packers’ Jarrett Bush during a punt return in the second quarter of the Thursday night game of Oct. 2.

Tampa Bay wide receiver Louis Murphy was docked $11,025 on Friday for using abusive language toward an opponent after the Buccaneers scored a touchdown in a 37-31 loss to the New Orleans Saints last weekend.

Seattle right tackle Justin Britt was fined $8,268 for a late hit against Washington’s Bashaud Breeland, while Seahawks linebacker Bruce Irvin was fined $5,512 for wearing white cleats while the rest of the team wore black — a violation of league uniform rules.
