BOSTON (AP) — The Sabres haven’t been able to push the Bruins around on the ice.

What’s worse, Buffalo hasn’t been able to take advantage of their power plays when Boston pushes back.

The Sabres are 0-for-9 with a man advantage in the first two games of the playoff series against the Bruins, which is tied 1-1 as it shifts to Boston for Game 3 tonight at 7 at TD Garden (NESN, TNT). That’s after finishing the season without scoring on their last 22 power plays over the final seven games.

“It’s always a concern, for sure,” said Sabres coach Lindy Ruff, who last celebrated a power-play goal in March. “I think we’ll have to tweak some things.”

The Sabres came into the series offended by a comment that Bruins coach Marco Sturm made about being the bigger and stronger team. Neither team backed down on Tuesday night, when they had several fights and a combined 94 penalty minutes.

“It’s a seven-game series so you see those guys all the time and there’s game inside the game, obviously,” Bruins defenseman Nikita Zadorov said. “Emotions are really high, everybody wants to win, everybody is competitive on the ice, so sometimes you just ended up in the scrums and the fights like that.”

Ruff wouldn’t rule out the possibility of a goalie change after Ukko-Pekka Luukkonen was pulled 16 seconds into the third period in Game 2 after his fourth goal of the game — one of them on a lofted dump-in from center ice. Alex Lyon stopped all seven shots he faced the rest of the way.

The two goalies shared the starting role this season, but Luukkonen won the No. 1 job by closing the season 12-2-1; Lyon was out the final week with an unspecified lower-body injury. Lyon went 20-10-4 for the season.

Ruff refused to blame Luukkonen’s spotty play for the Game 2 loss by saying “we win together, we lose together.”

But he also said: “(Lyon) may play next game.”

Slow starts have also been an issue. The Sabres have fallen behind in both games — 2-0 in the first one, and 4-0 in the second, failing to score in each until the final eight minutes of the third period. They came back to win 4-3 in Game 1 but rallied too late while losing 4-2 in Game 2.

“It’s been two games. It’s nothing to freak out about, and we know that,” Sabres forward Zach Benson said. “And we know we’ve got to be better, and we will be.”
