The Washington Redskins will be without three players for Sunday's tilt with the Chicago Bears including running back Chris Thompson, the team's top pass catcher out of the backfield.

Washington Redskins head coach Jay Gruden on Friday announced that running back Chris Thompson, safety Jeron Johnson and linebacker Perry Riley Jr. have been ruled out of Sunday's game against the Chicago Bears.

While the signing of veteran running back Pierre Thomas indicated that Thompson, who is dealing with a torn labrum in his shoulder, probably wouldn't play on Sunday against the Chicago Bears, Gruden confirmed that the third-year running back will be inactive against the Bears.

"He's made a lot of progress already, which is very good and that's a good sign," Gruden said. "But we'll see how it goes early into next week and go from there, and see where we stand with the running back situation."

Thompson suffered a joint AC sprain in his shoulder during the Redskins' victory over the New York Giants Week 12, and suffered a separate torn labrum injury against the Dallas Cowboys, tallying a carry for six yards and four receptions for 18 yards on 17 snaps.

Johnson, meanwhile, did not participate in practice this week as he's dealing with a hamstring injury.

This is the second time this season that the Boise State product has been hampered by a hamstring injury, as he also was sidelined during training camp.

With defensive back DeAngelo Hall now listed as the starting strong safety on the unofficial depth chart and other options as well, the Redskins will push forward without Johnson in Chicago.

"Kyshoen [Jarrett] is back at safety, pretty much, full-time role now," Gruden said. "Luckily, like I've said before, all those guys have taken a little piece of it. We have three solid safeties going in and, really, [Deshazor] Everett if he can play this week, he's been playing a little bit of safety, too, to maybe a fill in as a fourth. We should have it covered but we are a little thin with experience."

Gruden announced last week that Riley Jr. would be out for three to six weeks, and linebacker Mason Foster replaced him in the starting lineup, collecting six tackles and a forced fumble and fumble recovery each against the Cowboys.

Linebacker Keenan Robinson was active Monday night for the first time since the Redskins' Week 9 game against the New England Patriots, but did not record any reps as an emergency backup.

He was limited in practice this week and is questionable.

Tight end Derek Carrier (ankle/Achillies) will also be listed as questionable.

The third-year Beloit College product missed the matchup with the Cowboys, as the Redskins resorted to their "giant" package featuring Tom Compton as an eligible receiver.

"He was full today, yes, and he had a good day," Gruden said. "You know, it's just a matter of with the injury that he has, you know, making sure nothing happened out there today and he'll get some more treatment and see how he's feeling tomorrow. But I think it's looking positive for Derek."

Wide receiver Andre Roberts (knee) was not active last week as Rashad Ross took full kick return duties against Dallas. He did not participate in practices this week, but is listed as questionable.

Defensive end Jason Hatcher (neck/ankle) is also listed as questionable after he was limited in Thursday's and Friday's practices. 

Hatcher has felt better as the week has wore on after suffering a neck injury in Monday's loss to the Cowboys.

"When it first happened, I was scared that I wasn't going to have an opportunity to play," Hatcher said. "The strength is coming back slowly and at this point it's like mind over matter. I know how important this game is, and I know how important it is to be out there on the field with the team."

Linebacker Will Compton (shoulder), cornerback Quinton Dunbar (finger), cornerback Deshazor Everett (hamstring), safety Dashon Goldson (knee/hamstring/wrist) and Hall (toe) are all listed as probable.

The Redskins announced on Friday that defensive end Stephen Paea (toe) has been placed on the season-ending Injured Reserve list.
