"In a nutshell, I just didn't feel he got enough out of our group collectively," Flyers general manager Ron Hextall said in making the announcement.
Berube got the Flyers into the Stanley Cup Playoffs last season, but they finished 14 points out of a playoff spot this season.
Hextall said he made the decision Thursday and informed Berube on Friday.
"It's just a process that I went through," Hextall said. "I wanted to make the right decision. Once I put all the facts together, then you go with your gut and I came up with the decision last night."
