DALLAS -- The Dallas Stars needed to head into the NHL All-Star break on a positive note.

That mission was accomplished. Patrick Sharp scored two goals, and Kari Lehtonen stopped 21 shots in relief of starter Antti Niemi as the Stars outlasted the Buffalo Sabres 4-3 Thursday at American Airlines Center.

"It's really important," Stars coach Lindy Ruff said. "You can feel the frustration. Give them credit for digging in, fighting back. We got down by a couple, and I thought we did a good job getting back in it."

Jamie Benn and Tyler Seguin also scored for Dallas (20-20-10), which snapped a three-game winless streak and outshot Buffalo 37-27.

Buffalo (20-19-9) got two goals and an assist from Evander Kane and another goal from Matt Moulson but saw its three-game winning streak end. Anders Nilsson made 33 saves.

The Sabres nearly tied the game 9:02 into the third period after Lehtonen denied an initial shot from Rasmus Ristolainen. William Carrier and Zemgus Girgensons attempted to knock in the rebound, but Esa Lindell knocked the puck out of the crease with his glove to preserve Dallas' 4-3 lead.

Buffalo's Sam Reinhart appeared to make it 4-4 on a backhand with 9:54 remaining, but since the puck was sitting under Lehtonen, replays during an official-ordered review were inconclusive and the play was called no goal.

"I don't know if it was tough to see on the video or what, but it was 100 percent over the line, so it's a tough one," Reinhart said. "If the reason is they couldn't determine or couldn't see it, that's probably pretty fair because the goalie was on top of it. It's a little frustrating when you're behind the net and you see it in."

Nilsson left the ice with 28 seconds remaining, but the Sabres couldn't find an equalizer, even with several quality opportunities at close range.

Officials had one last review after the final whistle to determine if the puck crossed the goal line on a Ryan O'Reilly shot with 11 seconds remaining during a flurry of activity in front of the Dallas net, but a lengthy review determined it did not.

"Well, the puck goes through (Zach) Bogosian and into the net. The view, it's not super clear I guess in terms of definitively saying where it ends up," Sabres coach Dan Bylsma said. "It hits on (Lehtonen's) pad or it sits on the side of his pants. I think the answer is they don't definitively know that it crossed the whole goal line. I think we can all see it past the crossbar. That's the answer."

Kane gave Buffalo an early lead with his 13th goal of the season at 3:44, blowing by John Klingberg before beating Niemi with a forehand.

Dallas allowed the first goal in a seventh consecutive game, and the Stars are 2-3-2 in that span.

The Sabres doubled that lead at 9:30 of the first period when Moulson scored a power-play goal with a tip-in at the near post. Kane picked up the primary assist by feeding Moulson after skating around the back of the Dallas goal.

Dallas got on the board with 9:01 left in the first period when Sharp scored his fifth goal of the season on a wrist shot from the left point, which beat Nilsson far post -- the first of four unanswered goals for the Stars.

Lehtonen replaced Niemi, who stopped three of five shots, to start the second period. It was Lehtonen's seventh consecutive appearance, while Niemi was pulled for a third straight game.

Dallas tied it 42 seconds into the second period when Benn scored a power-play goal. Benn sent a wrist shot under Nilsson's glove from the right circle for his 13th goal of the season.

Bylsma used a coach's challenge on Benn's goal, asserting that Patrick Eaves was offside. However, replays proved inconclusive, so the goal stood.

Sharp added his second goal when he sent a wrist shot under Nilsson's blocker with 6:44 remaining in the second period from the left circle, giving Dallas its first lead at 3-2.

"It's been an up-and-down 50 games," Sharp said. "We haven't hit our stride that we're capable of. The last three, four, five games we've played really well. Hopefully, that's a sign of things to come."

Seguin made it 4-2 with his 18th goal of the season 4:36 before the second intermission. Seguin's shot trickled under Nilsson before the puck was accidentally tapped in by Cody Franson.

Kane scored again with 1:05 remaining in the second period off a turnover to make it 4-3. Kane intercepted an attempted clearance by Sharp at the right point and beat Lehtonen, who was screened by Brian Gionta, with a well-placed wrist shot.
