Destructive prop Sheridan and rookie scrum-half Wigglesworth are likely to feature against the Warriors following their heroics in Saturday's 24-13 triumph over France.
Sale director of rugby Philippe Saint Andre said: "The spirit in the camp is fantastic.
"We have real competition for places in every position, but the coaches can only choose 15 players to start the match on Friday night."
Scotland winger Rory Lamont returns after the 34-13 defeat by Ireland and is joined by club captain Jason White, who missed the Croke Park showdown with concussion.
France prop Lionel Faure is also included in Saint Andre's selection plans.
