Nose tackle and fullback Linval Joseph was back at practice Friday for the Vikings and expects to play Sunday at Washington.

Joseph, a top run-stopper who also lined up in the backfield for two plays last weekend, had missed the previous two practices with a shoulder injury. He was listed as questionable after being limited in the workout.

“I’m ready go, man,” Joseph said. “Can’t wait for Sunday.’’

Cornerback and punt returner Marcus Sherels was ruled out after suffering an ankle injury in last weekend’s 22-16 loss to Detroit. Wide receivers Stefon Diggs and Adam Thielen will be available to handle punt-return duties.

Cornerback Captain Munnerlyn returned to practice on a limited basis after sitting out the previous two days with an ankle injury, and was listed as questionable. If Munnerlyn, who did not express optimism about playing, can’t go, he will be replaced as the nickel back by starting cornerback Terence Newman, with Trae Waynes then entering the game.

“I think he’s going to do a fantastic job,” Munnerlyn said of Newman. “He’s a smart guy. … He’s tough. Man, you got to be tough to play inside. You got to make tackles. I think he’s going to step up and do a great job.”

Ruled out Sunday for the eighth straight game was defensive tackle Sharrif Floyd, who hasn’t played since the Sept. 11 opener because of a knee injury. But Floyd, who was rehabbing away from the team for about 10 days before returning Thursday, did do some work on the side during practice.

Also questionable are wide receiver Laquon Treadwell (hamstring), who didn’t practice Friday, and offensive lineman Zac Kerin (hand), who was limited.

The Redskins listed wide receiver DeSean Jackson (shoulder) as doubtful and tackle Morgan Moses (ankle) and safeties Will Blackmon (thumb) and Duke Ihenacho (concussion) as questionable.
