Washington Redskins running back Adrian Peterson avoided a major injury after dislocating his shoulder during Monday’s loss to the New Orleans Saints, and he has been diagnosed with a shoulder sprain, according to a person with knowledge of the injury who spoke on the condition of anonymity.

It is unclear if Peterson will miss any games. Coach Jay Gruden said Peterson is day-to-day and officially listed him as limited, although the team had only a walk-through Wednesday. He was also listed with ankle and knee injuries on the official report. Gruden also said that wide receiver Paul Richardson, who hurt his knee during the Saints game, is day-to-day. He’s also been nursing a shoulder injury in recent weeks.

“I’m not optimistic or pessimistic [about] either one [of Peterson and Richardson] right now,” Gruden said. “I’m just going to wait and see . . . They’re both pretty sore, but they’re both very tough guys. I just have to wait to see what the trainers say.”

The entire starting wide receiver corps was listed as limited, and Gruden said Jamison Crowder (ankle) and Richardson would not have participated in a normal practice. Josh Doctson continues to recover from a heel injury that Gruden described as painful every time he puts on his shoe. Doctson was seen walking without a boot or anything else on his foot, and Gruden added that the injury shouldn’t keep him from playing in Sunday’s home game against the Carolina Panthers. In the locker room, there was a medical scooter next to Crowder’s locker that is typically used to avoid walking on one foot.

Running back Chris Thompson, who suffered an injury to his ribs during the New Orleans game, was listed as limited, as were guards Shawn Lauvao (calf) and Brandon Scherff (knee), tackle Trent Williams (knee), tight end Vernon Davis (hamstring) and linebacker Zach Vigil (thigh). Thompson was also listed with a knee injury.

Peterson said he dislocated his shoulder during the first half of the 43-19 loss to the Saints. He did not have a single carry in the second half and finished with six rushing yards on four carries and 36 yards on two receptions. He leads the team with 242 rushing yards and three rushing touchdowns this season and has seven receptions for 136 yards.

He had sounded confident after the game that he would be okay, and an MRI exam confirmed that he had suffered no major damage, the person with knowledge of the injury said.

The Redskins have been decimated by injuries at running back, some of which led to Peterson being signed in the first place. Rookie Derrius Guice tore an anterior cruciate ligament in the team’s first preseason game. Rob Kelley (toe) and Byron Marshall (knee) are also on injured reserve.

Doctson missed Monday’s game and Lauvao was out the past two, although Doctson was close to being ready against the Saints. Gruden, however, made the decision to hold the former first-round pick out. Maurice Harris started in place of Doctson while Chase Roullier has slid to guard with Lauvao out and Tony Bergstrom has started at center.

“It’s just a nagging deal,” Gruden said about Doctson. “Think about a swollen heel or a sore heel. Every time you put your shoe on and run, it’s going to be a nagging-type deal. I don’t think it’s anything that’ll keep him out of the lineup . . . in the next few weeks.”
