Linval Joseph returned to practice Friday, a sign he could play Sunday in Washington.

Joseph is officially listed as questionable to play against the Redskins after a shoulder injury held him out of practices on Wednesday and Thursday. He rejoined the Vikings defense during the team's punt return drill on Friday. The Vikings' stalwart nose tackle has not missed a game this season.

"Today was a good day," Joseph said after he was limited in practice, adding that he expects to play Sunday.

Cornerback Captain Munnerlyn is also listed questionable after being limited in a Friday return to practice. Munnerlyn had his sprained right ankle heavily taped. He was held out of practice on Wednesday and Thursday.

Also questionable for Sunday are receiver Laquon Treadwell (hamstring) and guard Zac Kerin (hand).

The Vikings will be without punt returner Marcus Sherels, who has been ruled out after missing practice all week due to an ankle injury. Receivers Adam Thielen and Stefon Diggs fielded punt returns in Friday's practice.

Defensive tackle Sharrif Floyd, who had been away from Winter Park for about 10 days seeing specialists for his injured knee, worked with athletic trainers on the side of practice. He has not practiced since his Sept. 22 surgery.

For the Redskins: WR DeSean Jackson (shoulder) is doubtful; S Will Blackmon (thumb), T Morgan Moses (ankle) and S Duke Ihenacho (concussion) are questionable.
