An incident between John Tortorella and Philadelphia Flyers defenseman Cam York this week contributed to a deteriorating relationship between coach and team that led to Tortorella’s firing on Thursday morning, a team source said.

The source said that after Tortorella benched York for the final 50 minutes of the Flyers’ game on Tuesday at Toronto, a confrontation took place between the two that did not turn physical but that “they probably both crossed the line.”

As a result, York was functionally scratched on Thursday in a victory over the Montreal Canadiens, although he sat on the bench for the entire game because the Flyers had no healthy extra players. Interim coach Brad Shaw called it a “disciplinary issue,” and the team source said the decision to sit York was made by general manager Daniel Briere, who felt the team needed to make a point with York — who is expected to return to the lineup on Saturday.

But he won’t be playing under Tortorella, who has not responded to multiple interview requests from The Athletic since his firing.

The disagreement with York, and subsequent comments that Tortorella made after the game, contributed to the coach’s firing on Thursday morning. But those two events were not isolated. Something began to shift around the trade deadline on March 7, according to the team source.

Up until then, Tortorella seemed to be on board with the moves that Briere made, as the Flyers traded respected leaders Scott Laughton and Erik Johnson, further reducing a roster that had lost top-nine forwards Morgan Frost and Joel Farabee about a month earlier. But there was a heaviness around the team stemming from some of Tortorella’s reactions in the days and weeks that followed.

A disconnect started to grow between Tortorella, the team and Flyers management, culminating on Tuesday in Toronto, where the coach’s postgame comments didn’t help his cause, either, according to the team source.

As colleague Pierre LeBrun reported on Friday morning, the timing of Tortorella’s dismissal “was surprising. The indication from the Flyers earlier this week was that they wanted to sit down after the season with the 66-year-old coach, who had another year on his deal, to see where he was at, mentally and physically.”

Shaw said on Friday that Tortorella “left a note in our (coaches) room and in the players’ room when he came and got his stuff. That’s the type of guy he is.”

There had seemingly been tension bubbling between Tortorella and York for the past few weeks. York was made a healthy scratch for a game on March 8, and later bemoaned the lack of communication from the coach.

“We haven’t talked much, so I’m not sure,” he told reporters two days later, when asked why he thought he was scratched.

He also added: “I mean, I’m not playing to prove him anything. I’m playing for the guys in this locker room and the logo on my chest. I’m not playing for him, necessarily, if that makes sense.”

On Friday, speaking for the first time since being benched and then punished, York said:  “I’m not going to get into the details of it. I will say this, I take full responsibility for my actions. It’s been addressed here in the locker room. It’s something that I’m going to put behind me and move on from. We’ve got eight games left here and that’s my focus right now. We’ll leave it at that.”

Still, he admitted frustration with watching the team get shellacked 7-2 by the Maple Leafs, as they had only five defensemen playing for the majority of the game at the end of a 10-day road trip.

“Obviously, sitting on the bench there in that type of game is never fun,” he said.  “Five (defensemen) is a tough thing to do and you never want to put your teammates in that type of situation.”

Shaw was asked whether he would do something like bench a player for 50 minutes, as Tortorella did on Tuesday.

“I’m not going to get into that,” he said. “I don’t want to answer a question that can be used against Torts. I don’t think it’s anybody’s best interests, so I’d rather not answer that.”

In 58 games this season, York has four goals and 11 assists for 15 points. The 24-year-old is a pending restricted free agent. There were discussions about a contract extension earlier in the season, but not much progress made.

York reiterated his desire to be a part of the Flyers’ future on Friday.

“This is where I want to be,” York said. “I’ve stated that. I love what’s going on here and I love what we’re building. It hasn’t been our (best) year, but it’s here. This is where I want to be, and I’m looking forward to the future.”

Regarding Tortorella, York said: “I have nothing bad to say. He taught me a lot of really good things and was a really good coach for me. I’m going to use a lot of the things that he taught me down the road in my career. He’s a really good coach, and I wish him the best of luck down the road.”
