Bruins general manager Peter Chiarelli said yesterday that authorities in Montreal have assured him that captain Zdeno Chara will not be hauled in for questioning or otherwise detained by the police when the team's first-round playoff series with the Canadiens shifts to Montreal for Games 3 and 4. "Nothing untoward will happen when we get up there," Chiarelli said. But that's not to say that Chiarelli isn't expecting the usual playoff hysteria in Montreal to be ratcheted up even more. It will be the B's first trip to Montreal since Chara ran Habs forward Max Pacioretty into a Bell Centre stanchion on March 8, giving the Canadien a concussion and a fractured vertebra. He's back skating lightly, but right now it looks like he's not ready to play. It was a hit that sent the province into a tizzy, which only got crazier when the NHL followed the letter of the law and chose not to suspend him. Police opened an investigation (and it remains open, a police spokesman told the Montreal Gazette yesterday), Quebec-based sponsors threatened to pull out and fans protested the league's approach to violence outside the Bell Centre. "I expect there to be obviously a heightened sense of emotion from the media, from the fans, from just people walking around the city," Chiarelli said. "You've seen how emotional it gets up there, so I think there will be a bit of a frenzy. So we're preparing for it and whatever happens, we'll deal with it." While Chiarelli said he didn't expect any security concerns, he was mulling the option of pulling his team out of the hockey hotbed for the two-day break between Games 3 and 4, possibly coming back to Boston.
