The Washington Redskins listed four offensive starters as questionable for Sunday’s game against the Carolina Panthers, including all three starting wide receivers.

Wide receivers Jamison Crowder (ankle), Josh Doctson (heel) and Paul Richardson Jr. (shoulder/knee) and running back Adrian Peterson (ankle/shoulder/knee) are all questionable. Crowder seems to be in the most in danger of missing the game after not practicing all week.

“He needs to get up and run,” Coach Jay Gruden said about Crowder. “That won’t happen — [with] a couple of these guys, I won’t know — until Sunday at about 9, 10 o’clock when they get on the field and see if they can run and do some things. We have everything covered if they can’t go, but there’s three or four of these guys on the list we have to wait and see on Sunday.”

Rookie safety Troy Apke (hamstring) has been ruled out, and guard Shawn Lauvao (calf) is officially doubtful after missing the last two games. Lauvao returned to practice in a limited capacity on Thursday, and Gruden wanted to see how the guard’s calf responded. He was still sore Friday and did not practice. Chase Roullier has moved to guard and Tony Bergstrom has started at center with Lauvao out.

Running back Chris Thompson (rib/knee) and linebacker Zach Vigil (thigh) are also questionable, but both practiced on Friday.

Richardson suffered the knee injury while making a 23-yard reception in the first quarter against the Saints on Monday night. He said he probably shouldn’t have continued playing and that the joint would be feeling better this week if he hadn’t but he chose to play through the injury. Richardson said he’ll have to see how his body feels after Friday’s workout and that he’ll be icing and rehabbing all the way up to game time.

“I don’t think that was smart; I should have spoke up,” Richardson said. “When we came out [in] the third quarter, it was killing me. I’m like, all right, let’s get this comeback, let’s get this comeback, and it just wasn’t happening. I just felt like I wasn’t helping out there. I felt like I was more of a liability out there.

“That messes your head up. I was just telling Doctson, he’s had his battles with injuries and I’ve had mine. . . . We don’t ask to be hurt. We’ve got to deal with hearing everybody’s opinion. Everybody feels like we get hurt on purpose. That’s a lot to deal with, dealing with injuries, especially guys that are labeled injury-prone. We’ve got to get our bodies right. It’s hard. This game is hard.”

Maurice Harris is the next wide receiver up if any of the three starters can’t play. If two are out, Harris is most likely to be used in the slot, since he’s able to play all three receiver spots, while Michael Floyd would be used outside.

The Panthers activated linebacker Thomas Davis after a four-game suspension and will have him back and paired with Luke Kuechly in a combination that Gruden called the best in the league.

Panthers linebacker Jared Norris (toe) was placed on injured reserve Friday and fellow linebacker Andre Smith (hamstring) and wide receiver Damiere Byrd (ankle) are both out for Sunday. Tight end Greg Olsen is officially questionable as he returns from a foot injury, but he practiced fully Friday.
