Dennis Seidenberg fired in the shot from between the circles and Chris Kelly appeared to deflect it in front, but Seidenberg has been credited with the goal, at least for now.
Regardless of who scored, the important thing is that the Bruins move back into the top spot in the Eastern Conference with the win.
They are now 21-2-1 since the start of November and have won seven straight. They will look to push that streak to eight on New Year's Eve in Dallas.
Overtime, 0:00, 1-1: The five-minute extra session is under way, with the sides skating 4 on 4 looking to earn the extra point up for grabs in this one.
End Regulation, 1-1: The Bruins survive a sloppy final minute as they struggled to get the puck out of their zone with the Coyotes buzzing around the Boston net, but they get this one to overtime and earn at least one point.
Third Period, 16:36, 1-1: Another strong shift by the Krejci line, keeping the Coyotes hemmed in their own zone and creating several solid scoring chances, but nothing gets past LaBarbera to break this stalemate.
Third Period, 14:08, 1-1: Cal O'Reilly gets a chance in front off a Bruins turnover by Krejci deep in his own zone, but Rask denies the backhand bid to keep this one tied.
Third Period, 10:23, 1-1: More than halfway through the third and still no breakthrough in this stalemate. The Bruins have carried the play for much of the third with an 8-3 edge in shots, but LaBarbera has been up to the task after getting pulled in his last start Monday against Los Angeles.
Third Period, 5:45, 1-1: Gregory Campbell goes hard into the net looking for a rebound and is shaken up after hitting his head on the crossbar.
Third Period, 2:54, 1-1: The Bruins answer with their best chance in a while as Brad Marchand is sent in alone by Tyler Seguin, but his wrister from between the circles is snagged by LaBarbera with a glove save.
Third Period, 1:48, 1-1: The Coyotes threaten with an odd-man rush, but Rask stops Radim Vrbata's shot from the right wing and the play is blown dead for a hand pass on the rebound.
Third Period, 0:00, 1-1: The final frame is under way, with the Bruins and Coyotes deadlocked at 1-1 with 20 minutes to play in regulation.
Second Intermission Notes: The Bruins and Coyotes played to a scoreless stalemate in the second, and will head to the third tied 1-1.
Boston continues to dominate the draws, winning at a 67-percent clip (20-10). Patrice Bergeron is 9-4 and David Krejci 6-1. That's just a small part of what Krejci has brought in this one. He has Boston's only goal and has created chances on just about every shift in a strong effort.
The Bruins have a slim 21-20 lead in hits, with Milan Lucic leading the way with four. Adam McQuaid has three hits despite sitting out 17 minutes for instigating a fight in the first with Raffi Torres, who delivered an illegal hit to the head on Andrew Ference, prompting McQuaid's rather decisive response.
The Bruins have dominated the third period this season, outscoring opponents 50-22, and they'll need another big final frame in this one.
End Second Period, 1-1: The middle frame comes to a close with no scoring as it remains 1-1, but Zach Hamill nearly had his first NHL goal with a bid in close at the right post with 16 seconds left in the period.
Second Period, 17:46, 1-1: The Bruins kill off the penalty with Rask robing Whitney at the right post with a sprawling toe save and Chara leading a helping hand later by clearing a rebound out of the crease behind Rask.
Second Period, 15:46, 1-1: The Coyotes get their first power-play chance of the night as Johnny Boychuk is called for tripping Shane Doan. Boychuk upended him diving to try to break up a 3-on-1 rush after Chara got caught up ice.
Second Period, 14:28, 1-1: Daniel Paille crashes into LaBarbera trying to bang home a feed at the left post. That draws a whistle, but no penalty on the play.
Second Period, 13:30, 1-1: Johnny Boychuk in pain after blocking a shot, but grits through rest of shift until the Bruins can finally clear the puck and he can hobble to bench for a change.
Second Period, 10:59, 1-1: Tempers flare again after a flurry in front of Rask. Shawn Thornton comes in to clear out Paul Bissonnette and the two tough guys exchange some chirps during the stoppage in play.
Second Period, 9:00, 1-1: The Krejci line continues to make an impact in this one with another shift that produced several good scoring chances. Krejci and Lucic in particular have really come to play in this one.
Second Period, 6:50, 1-1: A "Let's Go Bruins" chant rings out at Jobing.com Arena as the Bruins fans in Arizona make their presence felt.
Second Period, 4:30, 1-1: The Coyotes threaten as the puck jumps off Ference's stick for a turnover in front of the Bruins net. Rask makes the stop with Shane Doan set up at the left post and Ray Whitney trying to bank it in off Rask from behind the goal.
Second Period, 0:00, 1-1: The middle frame is under way in Phoenix, where the Bruins and Coyotes are tied 1-1 after a first period that got a little nasty.
First Intermission Notes: Solid first period back from the holiday break for the Bruins, who jumped out to a quick lead with a David Krejci goal less than a minute in. Phoenix tied it late in the frame, but overall still a solid period for Boston to kick off a three-game road trip.
Krejci was particularly impressive. In addition to his goal, he's skating with a little extra jump in his step and has created several chances. He's also 3-1 on faceoffs, helping the Bruins continue their domination in that category. Boston leads 13-6 (68 percent) overall, with Patrice Bergeron as usual leading the way at 6-2.
Brad Marchand continues his strong play, picking up another point with an assist on Krejci's goal and chipping in two shots and a hit. Tuukka Rask had his shutout streak snapped at 170:26 when Ray Whitney beat him 5-hole, but Rask still looked sharp for most of the frame as Phoenix had a slim 10-9 edge in shots.
The Bruins will have to play without Adam McQuaid for a while. he was tagged for 17 minutes in penalties after instigating a fight with Raffi Torres, but he got his money's worth as he tagged Torres plenty and left the former Canuck agitator bloodied. Torres earned that beatdown after a dirty shot to Andrew Ference's head. The Bruins won't mind McQuaid spending some extra time in the box to address that kind of cheap shot.
End First Period, 1-1: The first 20 minutes are in the books, with the game even at 1-1 and tempers still flaring with some words and shoves at teh final buzzer.
First Period, 17:11, 1-1: Things get nasty as Raffi Torres delivers an elbow to the head of Andrew Ference. Adam McQuaid takes exception and dominates fight with Torres, who leaves bloodied and beaten.
Torres gets an extra minor for elbowing, while McQuaid gets tagged with two for instigating and a misconduct as well as his fighting major so the sides remain even.
First Period, 15:16, 1-1: The Coyotes pull even as Ray Whitney makes an impressive drive to the net.
Whitney spilt the defenders down low, cutting between Chara and Johnny Boychuk before beating Rask 5-hole.
First Period, 14:15, Bruins 1-0: Tuukka Rask comes up big stuffing Taylor Pyatt's attempt at the right post as the Phoenix fourth line creates some pressure in the Bruins zone.
First Period, 11:40, Bruins 1-0: Zdeno Chara continues to be very active on the attack, going in deep from a chance down as the Bergeron line creates more pressure in the Phoenix zone.
First Period, 6:17, Bruins 1-0: Coyotes tough guy Paul Bissonnette with a shot on Gregory Campbell in front of the Bruins net. That draws Chara over for a shove in return but nothing further develops.
First Period, 3:43, Bruins 1-0: The Bruins continue to pressure Phoenix with Zdeno Chara and Brad Marchand each putting bids on net to challenge LaBarbera, who has been shaky.
First Period, 0:47, Bruins 1-0: The Bruins need less than a minute to jump out to a quick lead as David Krejci strikes just 47 seconds into play.
After a rush was broken up just inside the Phoenix blue line, Krejci pounced on the loose puck and quickly fired a shot in through the traffic in front.
First Period, 0:00, 0-0: And they're under way in Phoenix, where the Bruins will look to pick up where they left off before the holiday break and extend their latest win streak to seven games.
9 p.m.: The Bruins will open with the line of reigning NHL First Star of the Week Brad Marchand, Patrice Bergeron and Tyler Seguin up front, Zdeno Chara and Dennis Seidenberg on defense and Tuukka Rask in goal.
The Coyotes counter with Ray Whitney, Daymond Langkow and Shane Doan up front, David Schlemko and Rostoslav Klesla on the blue line and Jason LaBarbera in net.
8:55 p.m.: Rich Peverley (undisclosed injury and Steven Kampfer are officially the scratches for the Bruins.
Martin Hanzal, Boyd Gordon, Adian Aucoin and mike Smith are out with injuries for the Coyotes, who also scratch David Rundblad and Patrick O'Sullivan. Call-up Andy Miele is in the lineup in place of O'Sullivan.
8:30 p.m.: Tuukka Rask did lead the Bruins out for the warm-up in Phoenix and will get the start as expected.
Jason LaBarbera gets the nod for the Coyotes despite being pulled after allowing four goals on 29 shots in his last start Monday against Los Angeles.
8 p.m.: The Bruins get back to work in about an hour as they open a three-game road trip in Phoenix.
They'll do it without forward Rich Peverley once again, as he will remain out for another game with an undisclosed injury. Peverley did participate in the morning skate and the Bruins hope to have him back in gthe lineup Saturday in Dallas.
Bruins coach Claude Julien also revealed after the morning skate that he plans to start Tuukka Rask in net for this one. Rask bring s 155:10 shutout streak into the contest after back-to-back blankings of Florida and Los Angeles in his last two starts.
8 a.m. ET: The Bruins return from their Christmas break and begin a three-game road trip with a stop in Phoenix on Wednesday.
It's the first meeting between the clubs since they faced off for two games in Prague to begin the 2010-11 season. They split those encounters, with the Coyotes taking the opening game 5-2 and Boston winning the rematch 3-0 behind a 29-save shutout by Tim Thomas.
That was just the start of a historic season for Thomas — and the Bruins. Boston went on to win the Cup, and they look even better this season as they head to Phoenix riding a six-game winning streak and a 20-2-1 roll since the start of November.
Things haven't been nearly as hot out in the desert of late, with Phoenix just 5-8-0 in December. That includes a 1-4-0 mark at home. Overall, the Coyotes are 18-15-3 and 10th in the West, but are just one point out of the final playoff spot.
The Coyotes are without starting goalie Mike Smith, who is on injured reserve with a groin problem. Backup Jason LaBarbara was pulled in favor of Curtis McElhinney on Monday after allowing four goals on 29 shots in a 4-3 loss to Los Angeles. Defenseman Adrian Aucoin (lower body) and forwards Martin Hanzal (upper body) and Boyd Gordon (lower body) are also battling injuries.
The Bruins haven't been hit too hard by injuries this year, but they are likely to remain without forward Rich Peverley on Wednesday. He was rested last week to deal with an undisclosed nagging injury, but still did not practice with the team on Tuesday.
The puck drops at 9 p.m., so check back here for updates on all the action.
