Ruff is keeping his forward lines and defensive pairs identical from Dallas' 3-2 win in Game 4 at XCel Energy Center on Wednesday.
Goalie Antti Niemi, who made 28 saves in Game 4, his first start of the series, was first off the ice at morning skate and will start for Dallas, who leads the best-of-7 series 3-1.
Center Jason Spezza, second on the Stars with four points (two goals) in the series, expects another tough game with the Wild on Friday.
"You're playing against a team that's looking to try to stay alive," Spezza said. "They're going to throw everything at us. We're happy to be back home, [we want to] use the crowd to our advantage and try to win the special teams battle again."
Dallas center Tyler Seguin will miss a third consecutive game due to an issue associated with a partially-cut Achilles in March. Seguin, second on the Stars with 73 points this season, missed Game 1 before returning for Game 2, when he looked rusty and hasn't played since.
Wild interim coach John Torchetti appears to be making two changes to his lineup. On the second line, Jordan Schroeder likely will replace Justin Fontaine on the right side of the second line alongside Jason Zucker on the left and Charlie Coyle at center.
"To the team, he [Schroeder] brings a lot of speed," Torchetti said. "[He's] good on the forecheck, [he can] pressure the puck, good on neutral-zone transitions, good on entries. We like his speed a lot."
Torchetti also appears to be replacing center Zac Dalpe on the fourth line with Jarret Stoll, who will skate alongside Chris Porter on the left and Kurtis Gabriel on the right.
Stoll, a healthy scratch in Games 3 and 4, is ready to make an impact in Game 5.
"You never want to sit out," Stoll said. "You always want to your help your team win, and be in the locker room with the guys, and battling on the ice with the guys. It will be good to get back in tonight."
Torchetti is keeping his defensive pairs identical from Game 4. Goalie Devan Dubnyk was first off the ice at morning skate and will start his fifth consecutive game of the series.
