Dallas, 5-1-0 in its past six games, can take a step toward securing first place in the Central Division with a victory Thursday. The Stars are tied in points with the St. Louis Blues, but hold the regulation/overtime wins tiebreaker 44-41. The Blues will have one game in hand following games Thursday.
The Stars, who clinched a playoff berth with a 6-2 win at the Chicago Blackhawks on March 22, are bidding for their first division title since 2005-06, when Dallas won the Pacific Division with 112 points but lost to the Colorado Avalanche in the 2006 Western Conference Quarterfinals.
Ruff is keeping his forward lines and defensive pairings identical from a 5-2 win against the Nashville Predators on Tuesday.
However, goalie Antti Niemi was first off the ice at morning skate and will start against Arizona after Kari Lehtonen started against Nashville.
"I thought he was rock solid. He played a heck of a game [on Tuesday], he stood tall," Ruff said of Niemi's performance against the Predators. "For me, he looked real sharp."
Arizona coach Dave Tippett made morning skate optional on Thursday but said after practice on Wednesday that Mike Smith would start in goal against Dallas.
Coyotes captain Shane Doan, who missed a 5-2 loss to the Calgary Flames on Monday with an upper-body injury, is likely to return, Tippett said.
Doan likely will play right wing on Arizona's third line, with Jordan Martinook on the left and Brad Richardson at center.
Tippett kept his top line of Max Domi, Martin Hanzal and Anthony Duclair intact from the Calgary game, but shuffled his bottom three lines.
Tippett also is making one change to his second defensive pair, with Alex Grant likely replacing Nicklas Grossmann, alongside Klas Dahlbeck.
Grant, who has two games of NHL experience with the Anaheim Ducks during the 2013-14 season, would be making his Coyotes debut.
"Well, he's a big defenseman that moves the puck well," Tippett said of Grant. "With the injury to [Michael] Stone, it's an opportunity for him to come in and get some of those minutes. We want to evaluate all of our players and see where he's at."
Here are the projected lineups:
