PITTSBURGH -- Jake Guentzel had a goal and two assists for the Pittsburgh Penguins before he was injured in the third period of a 5-2 win against the Ottawa Senators at PPG Paints Arena on Monday.
The forward left the game after crashing into the end boards following his goal to put the Penguins ahead 5-2 at 6:55. He went to the locker room holding his right arm after scoring on a backhand for his 200th NHL point and tripping over Senators defenseman Thomas Chabot.
Guentzel, who leads Pittsburgh with 20 goals and 43 points, was being evaluated after the game. More information could be provided after the Penguins practice Tuesday, coach Mike Sullivan said.
"It was really scary," Sullivan said. "Those are always dangerous when you fall that distance from the boards."

Paul cut it to 2-1 on a wrist shot with Jarry scrambling to push toward the right post at 4:21 of the second before Malkin scored 1:41 later.
Malkin dropped to one knee for a wrist shot that made it 3-1 at 6:02. He has 15 points (five goals, 10 assists) during a personal nine-game point streak, a stretch that was interrupted by missing two games with an illness Dec. 12-14.
"I feel it, you know?" Malkin said. "I try to help the team to win. It's always good when you have a chance to score and you score, you feel it for the whole game after. Great game for us. We play against a tough team. No power play tonight. We play hard. Good two points for us."
Paul, who has three goals in the past two games, got the Senators within 3-2 when he scored on the rebound of a shot from Connor Brown at 15:58.

"We knew what we were coming into," Paul said. "We have to get back to playing a full 60 minutes hard. We can't take any letups. Just tighten up our game. Our neutral zone is usually our best part of our game. We're letting too many odd-man rushes. I think we just have to tighten up, play hard, and get back to the way we were."
Patric Hornqvist gave Pittsburgh a 4-2 lead when he scored from just outside the crease at 16:51.
Senators goalie Marcus Hogberg made 28 saves.

They said it
"As objectively as I can look at it, [the Penguins are] probably the best-coached team in the NHL. ... They get those chances because their fundamentals are so solid. They put pucks behind D. Their gaps are great. They just look really responsible. They kind of wear you down, and you have breakdowns, and it turns into these fancy Grade A [chances] for them. I think it can look a little misleading, but it's solid fundamentals by them, and they took it to us." -- Senators defenseman Mark Borowiecki
"I think the team is just playing a great team game. We're getting pucks deep and we're getting pucks in the net at key times. I think that's helped us a lot." -- Penguins goalie Tristan Jarry
