BOSTON (AP) -- A couple of goals, a couple of fights - it was a fitting way to honor Terry O'Reilly.

Brian Rolston scored to tie it in the third period and Steve Shields stopped 30 shots to remain unbeaten as the Boston Bruins celebrated Terry O'Reilly Night by tying the Ottawa Senators 2-2 on Thursday.

Rolston scored on a wrist shot coming across the middle to help the Bruins tie their home opener and move to 4-1-2. They have not lost since falling 5-1 to Minnesota in the season opener.

Jason Spezza, the Senators' top prospect who was making his NHL debut, made a nifty pass to assist in Ottawa's second goal. He fought off two defenders to backhand the pass to Marian Hossa, and he beat Shields to give Ottawa the lead 4:36 into the third.

"It's a step up, but I definitely think I can play here," Spezza said. "It makes it easier knowing I'm playing with such good hockey players."

Patrick Lalime stopped 26 shots for Ottawa, which has not lost since a 3-1 defeat to New Jersey in its season opener.

The Bruins retired O'Reilly's No. 24 before the game with a ceremony in which Ray Bourque called the former captain "the ultimate Bruin." Known for his hard work and toughness more than his swiftness on skates, O'Reilly is still the team's career leader with 2,095 penalty minutes.

So it was no surprise that a video montage of his career highlights was heavy on fighting and less focused on goal-scoring; when it came time for him to join the ceremony, he came out of the penalty box, so the fans would recognize him.

"You were patient with me as I stumbled and slipped through my first few years and through my last few years," he said. "I loved playing hockey for you people and this will always be my home."

In the first, when Boston's Sean Brown and Ottawa's Dennis Bonvie squared off to fight, the crowd chanted "Terry!" and the referees seemed to give them extra time before breaking it up. Michal Grosek and Wade Redden matched up in the second, but it was far from the glove-throwing, over-the boards and into-the-stands anarchy that made O'Reilly such a favorite of his fans and teammates.

"It was a rush seeing all the guys that were Bruins before us," said Boston defenseman Hal Gill, who scored just 22 seconds into the game when he lofted a shot from the blue line past Lalime. "You get chills."

Ottawa appeared to tie it with 14 seconds left in the first when Mike Fisher kicked the puck in as he was pushed into the crease by Bruins defenseman Don Sweeney. After a video review, the goal was disallowed.

"They went upstairs and they said it was kicked in. He didn't kick it in. The puck hit him," Senators coach Jacques Martin said. "He was off balance because he was getting tripped."

Shields' biggest save of the night came midway through the second when he stopped Hossa on a breakaway. But the Senators made it 1-all on Daniel Alfredsson's goal at 14:00 of the second.

Spezza was called up because Radek Bonk is out with a chest injury. ... Bruins forward Sergei Samsonov missed his third consecutive game with strained ligaments in his right wrist.
