Tortorella went to Calgary's locker room at intermission following the first period Saturday night, which began with a handful of fights and four game misconducts per team.
"Mr. Tortorella's actions in attempting to enter the Calgary Flames locker room after the first period were both dangerous and an embarrassment to the league," NHL senior executive vice president of hockey operations Colin Campbell said in announcing the suspension. "Coaches in the NHL bear the responsibility of providing leadership, even when emotions run high, and Mr. Tortorella failed in his responsibility to the game."
Tortorella blamed Flames coach Bob Hartley for starting his fourth line, saying he couldn't put star players Daniel and Henrik Sedin at risk just to deflate the situation. Hartley was fined US$25,000 by the NHL.
"We are holding Mr. Hartley responsible for the actions of Flames' right wing Kevin Westgarth, who took the game's opening face-off and attempted to instigate a premeditated fight with an unwilling opponent — the Canucks' Kevin Bieksa," Campbell said.
This is the second career suspension for Tortorella, who missed Game 6 of the 2009 Eastern Conference quarter-finals as coach of the New York Rangers for throwing a water bottle into the stands in Washington.
Tortorella's suspension begins Tuesday night with Vancouver's game at the Edmonton Oilers and runs through Feb. 2.
