Patrice Bergeron skated for the second straight day on Sunday, an encouraging sign as the Bruins await the concussed center’s return to the lineup. Coach Claude Julien made clear Sunday at TD Garden that while Bergeron is progressing, the team has zero intention of rushing the 25-year-old back into the lineup.

“If he’s not 100 percent, he will never play,” Julien said. “Whether it’s regular season or playoffs, our organization, even before they tightened up the rules on that, there is no way we would ever do that to a player. That is too important to his personal lifestyle and the life he is going to lead after hockey that, that will always come before the game. It’s unfortunate, but that’s the way it should be.

“We believe in that and we are going to continue to enforce it, so the day you see Bergy back in our line-up, he will be 100 percent. If he’s not, you’re not going to see him.”

The concussion , which Bergeron suffered in the third period of Game 4 of the conference semifinals, is the third of the young center’s career. Bergeron leads the Bruins with 12 points this postseason.
