The Flames have not lost a game in Nashville since Jan. 18, 2008. Dating back to the start of last season, the road team has won the past five matchups in the series.
"It was kind of a broken play," Bourque said. "I think (Morrison) just tried to get it on net. It bounced in the air, hit my shoulder, went down to the ice, and I don't think the goalie knew where it was. It got to my stick, and that is when I shot it in the net."
The goal was the first of the season for Bourque, who had missed the Flames' previous two games with a concussion.
"As the game went along, he got better and better," Calgary coach Brent Sutter said. "I thought in the last 12 minutes of the third period he really started playing that big-man's game where he had the puck a lot on his stick in the offensive zone, and obviously got a big goal for us in overtime."
Flames goaltender Miikka Kiprusoff stopped 34 shots for his first shutout of the season and 35th of his career.
"In this building, they go hard from the start," Kiprusoff said. "They shoot a lot, and we knew that and we were ready for that."
Rinne matched Kiprusoff save for save until Bourque ended the game, stopping 34 of 35 shots in his first action since leaving with an injury in the third period of the Predators' opener on Oct. 9.
"I've been practicing pretty well the last few days, and I only missed three games, so it was not a huge break," Rinne said. "I was a little more nervous than usual, but it was still a good game for me."
The Predators lost defenseman Ryan Suter a little more than two minutes into the game with what the team called a lower-body injury. He collided with Calgary defenseman Cory Sarich in front of the Nashville bench at 2:01 of the first. Suter left the ice immediately and did not return, but the Predators indicated the injury isn't serious.
"It is just a lower-body injury right now," Nashville coach Barry Trotz said. "He might miss a little bit of time, but nothing major."
