Zyuzin was standing in front of the net when right wing Martin St. Louis passed from the right corner. He beat Bruins goalie Byron Dafoe 14:49 into the period.

FEELING GOOD: Stan Drulia, who has missed the last eight games with a nagging back injury, is back in town after spending two days in St. Louis receiving treatment.
"I feel a lot better today than when I left," Drulia said before the Boston game.
The veteran right wing said the problem was diagnosed as swelling in his lower back. He was treated with two shots and skated pain-free for 15 minutes Friday.
Asked whether he was confident he could play against Toronto tonight, Drulia said, "That's what I'm here for."
STITCHED UP: Defenseman Pavel Kubina missed his first game in more than a month with an injured left index finger.
Kubina said he took nine stitches after a skate cut through his glove during the second period against Philadelphia on Thursday.
"My hand was kind of on the ice and one guy just skated over it," said Kubina, who has a team-high 64 blocked shots this season. "I didn't even feel it at first."
SCRATCHES: Defensemen Sergey Gusev and Kristian Kudroc were healthy scratches for the Lightning. Forwards Shawn Bates and Mikko Eloranta and defenseman Patrick Traverse were scratches for the Bruins.
