In 56 games, Pastrnak had 66 points (31 goals, 35 assists), which would have put him on pace for 96 points. His NHL career high is 80 points (35 goals, 45 assists) last season.
"On my way to the car, I slipped and I fell," said Pastrnak, speaking Monday for the first time since the injury. "It was unfortunate that I got hurt from it. I was really upset. It would be the last thing I wanted to do. Four weeks in the gym, skating with no stick. Obviously, these things happen in life and I just try to take advantage and get better as a player."
Pastrnak said he had a feeling immediately that something was wrong. Being left handed, he braced himself with his left hand, which resulted in the injury. He said it did not feel right as soon as he got up.
"I'm a lefty, so I usually put my left hand always first," he said. "Put all the weight on it. Maybe if that happened when I was 18 with 160 [pounds], that wouldn't hurt. But now I'm 190. Kind of hurt."
When he does return to the lineup, Pastrnak, who is tied with forward Brad Marchand for the team lead in goals, will once again skate on the top line with Marchand and Patrice Bergeron. But given that the team was pleased with Danton Heinen in that spot during Pastrnak's absence, it opens the door for Bruins coach Bruce Cassidy to move Pastrnak down to the second line as David Krejci's right wing, if he feels that could balance Boston's scoring.
"That's where he's going to start," Cassidy said. "It's a comfort level for him. And then we'll see."
Sweeney said last month, in announcing the injury, that Pastrnak was upset and disappointed by what had happened. The forward reiterated that on Monday.
"I let the guys down a bit," he said. "Obviously it's tough time, you know? It's not an injury that happened on the ice. I took full responsibility for that and obviously that's what hurt me most. Could I avoid it? Obviously, I wish and I think these things happen. But definitely the thing that I could let somebody down, I hate that. The first couple of weeks was tough."
