BUFFALO, N.Y. (AP) -- Valeri Nichushkin scored 51 seconds into the game and Antti Niemi stopped 24 shots to help the Dallas Stars beat the Buffalo Sabres 3-1 Tuesday night.
Jason Spezza and Tyler Seguin also scored, and Dallas won a late coach's challenge on the way to becoming the first NHL team to 15 wins this season. The Stars' 30 points are tied with Montreal and the New York Rangers for tops in the league.
Ryan O'Reilly's power-play goal with 6:57 to play broke Niemi's shutout bid. Sam Reinhart tied the score moments later only to see the goal overturned after Stars coach Lindy Ruff challenged the call, and video review showed Tyler Ennis to be offside.
It was the second time Buffalo had a goal overturned for offside after a coach's challenge.
Linus Ullmark made 26 saves for Buffalo, losers of two straight at home.
