The winger was reportedly threatened by the rugged Boston forward during the traditional on-ice handshake between teams at the end of a series. Lucic, a 25-year-old from Vancouver, aggressively shook hands and had words with Weise and defenceman Alexei Emelin.
"You know what? I'm going to say it once: I never went into detail about it," Weise said Friday. "I never made any comment on what he said.
"It got blown out of proportion. They read his lips. TSN did it or whatever. I never personally went into any detail about what he said. I believe that should stay on the ice, and we'll leave it at that."
The Bruin reportedly said: "I'm going to kill you next year," with an F-Bomb thrown in for good measure.
When told that Weise said he had been threatened, Lucic called him a "baby" for revealing what was said between players on the ice, violating one of hockey's unwritten rules.
Lucic and the Bruins were harshly criticized for what some called disrespectful acts and words during Montreal's seven-game win in the NHL Eastern Conference final.
But Canadiens centre Daniel Briere said it is unfair to blame the entire Boston team.
"The last few days we've heard a lot about Milan Lucic, his comments and all that," said Briere. "A lot of people are saying that's a reflection of the Bruins and it represents the team.
"But on the other hand, you have a player like Patrice Bergeron, who has all the class in the world. It's not fair to say it reflects on all the Bruins."
