Josh Bailey scored twice and Evgeni Nabokov stopped 30-of-31 shots as the Islanders beat the Bruins, 2-1, Thursday night at TD Garden. The Bruins (26-10-4) had their modest two-game win streak snapped and more importantly, fell back into second place in the Northeast Division, one point behind Montreal, which beat the Sabres in Buffalo.
The Bruins played their first game without Brad Marchand , who was diagnosed Thursday with a concussion . He becomes the second player on his line out of action with a concussion, though Patrice Bergeron  did return Thursday morning and participated in a light pre-game skate  at the Garden.
With Marchand out coach Claude Julien  was forced to juggle the lineups again, starting with a line Jaromir Jagr and Milan Lucic , and centered by Gregory Campbell . David Krejci  centered the line of Nathan Horton  and Daniel Paille .
Adam McQuaid returned after missing the previous 11 games with a shoulder injury. McQuaid’s return allowed Julien the chance to rest rookie defenseman Dougie Hamilton for the first time this season. The rookie had played in all 39 games before Thursday’s game.
The Bruins and Islanders appeared destined for a scoreless opening period before the Bruins allowed the Isles to break out on a 4-on-2. Bailey ripped off a shot from the top of the left circle that beat Tuukka Rask  to the top far corner with 20.5 seconds left in the first.
The Bruins got the goal back on a pretty power play feed from Campbell to Tyler Seguin  across the low slot. Seguin’s one-timer cleanly beat Nabokov 3:41 into the second for the equalizer. Despite the power play goal, the Islanders carried play though the period, outshooting Boston, 19-8. The hard work paid off for the visitors when Bailey fired a bad-angle shot from the left circle on Rask. The Bruins goalie appeared to have the play covered but allowed the puck to leak through and the Islanders had their second one-goal lead of the night.
It could’ve been worse for the Bruins but Rask made a spectacular sprawling save on Matt Moulson with 10 minutes left in the second to keep the game tied, three minutes before Bailey’s second of the night put New York back on top.
Bailey looked for the hat trick with 5:45 left in the third but Rask made a save that kept the Bruins within one. The Bruins could not sustain any pressure in the Islanders end for most of the third period as the Bruins continued to all the opponent to rack up high shot totals. The Islanders finished with 36 shots on goal.
Rask was pulled with 1:23 left as the Bruins failed in their attempt to get the equalizer.
The Bruins are off Friday before taking on the Hurricanes in Raleigh, N.C. on Saturday night. For more from DJ Bean and Mike Petraglia from the Garden, visit the Bruins team page at weei.com/bruins .
