The Edmonton Oilers may have to start a goalie who hasn't won in nearly two years against the Boston Bruins on Wednesday.

Third-stringer Richard Bachman's only appearances this season came in Monday's shootout loss to the Winnipeg Jets and a 7-2 loss to Ottawa on Saturday, when he allowed four goals in relief of Viktor Fasth. Bachman hasn't won since April 13, 2013, while with Dallas.

With No. 1 netminder Ben Scrivens (hamstring) already on injured reserve, Fasth had started the past four games but got hurt Monday.

"All I got is just that it's a knee issue," coach Todd Nelson said. "We don't know how bad it is."

The Oilers are returning from a 2-3-1 road trip during which Jordan Eberle led the team with six points while Nail Yakupov, Ryan Nugent-Hopkins and Anton Lander scored three goals apiece. They've tried to fill the void left by Taylor Hall, who led the team in points the last two seasons, but has not played since Feb. 2 with an ankle injury and likely won't return this month.

Rask has dropped his last four starts and owns a 3.85 goals-against average in his last two.

Following a solid month of play to put themselves back in the heart of the Eastern Conference playoff picture, the Boston Bruins have abruptly fallen back into mediocrity.

The Bruins would reach a new low Wednesday night if they can't avoid their longest losing streak in five seasons, visiting the West's worst team and having not lost to the Edmonton Oilers in more than 14 years.

The most recent of Boston's four straight losses was a heartbreaking 4-3 overtime defeat to Calgary on Monday, having blown a three-goal lead. The game-winner came with 2.4 seconds remaining when a puck sent toward the front of the Bruins' net deflected off the stick of Boston's Brad Marchand and ended up behind goalie Tuukka Rask.

"That was obviously a very frustrating goal, but I don't think we can blame it on that," Marchand said. "We let the game go a long time before that. That just kind of ended it on a sour note."

The skid follows a brilliant January in which the Bruins went 8-1-3 and allowed a league-best 1.58 goals per game. That month placed Boston within seven points of the East lead, but after five losses in six tries in February, that deficit has doubled while the Bruins (28-20-8) have barely kept hold of a wild-card spot.

Another loss Wednesday would mark the Bruins' longest losing streak since dropping 10 straight Jan. 16-Feb. 6, 2010.

"I think in January, we had done a good job getting ourselves back in that playoff position but if you look at it, we're barely there, so there's still lots of work to be done and lots of points to be had," Chris Kelly told the Bruins' official website prior to Monday's loss.

Boston has gotten two points in every matchup with the Oilers since losing in Edmonton on Oct. 17, 2000. The Bruins have won the last 13 meetings while shutting out the Oilers five times and holding them to 20 goals.

The last time Boston's struggling power play scored more than once was in a 5-2 win over Edmonton on Nov. 6. Only league-worst Buffalo has scored fewer power-play goals than the Bruins' 22, and they've failed to get one in four straight games.

The Oilers (16-32-10) have allowed three power-play goals in their last two games and 11 overall.
