As comebacks go, the Devils staged one Saturday night that can easily be classified as improbable and unforgettable.

They scored two goals in the final 68 seconds, including the tying goal in which goalie Martin Brodeur was pulled to create an unusual six-against-three power play advantage.

But was their stunning 4-3 victory over the Boston Bruins, their first at TD Garden in four years, the kind of performance that can turn their season around?

“We can talk about it in 20 games maybe whether this was a momentum-changer,” Devils forward Patrik Elias said. “We hope so. It was a big win against a really good team. It’s tough to play against these guys. The power play was great for us, obviously.”

The power play, which has produced at least one goal in five straight games, went 4-for-7 to spearhead the Devils’ first win in Boston since a 2-1 shootout victory on Nov. 27, 2009.

“It’s huge,” Brodeur said after stopping 25 of 28 shots for his 670th career win and first of the season. “We talked about it (Friday) when we came in here that this could be something big for us as far as our confidence and knowing what we are able to achieve in certain situations.

“We didn’t just turtle and go home. We fought through this against a tough team. Records prove we’re not good against them. We don’t play well against Boston, especially in this building. It’s been real tough for us. We can’t get (too full of) ourselves. I thought we did a little bit with the Rangers, getting a little too high after that win. We have to stay grounded.”

That will be a challenge considering the magnitude of the comeback.

It actually started with a power play goal from Damien Brunner with 27.1 seconds remaining in the second period. That brought the Devils to within a goal, 3-2, but the Bruins were on a four-game winning streak for good reasons.
