This being the playoffs and all, Bruins coach Claude Julien wasn’t giving out a whole lot of information yesterday about injured center Patrice Bergeron, who left Game 5 in the second period and did not return. Bergeron was taken to a Chicago hospital for “observation,” according to the team, was discharged Saturday night and returned home yesterday on the team charter. Julien pronounced Bergeron’s condition as “day-to-day.” Asked if it was an upper- or lower-body injury, Julien only said it was a “body” injury. Sportsnet in Canada reported Saturday night that Bergeron was being evaluated for a possible spleen injury. Asked how he was on the flight, Julien adopted Brad Marchand’s wise-guy tone and said Bergeron looked “dashing in his suit.” “Guys, he’s day-to-day, and day-to-day is really good news to me. It should be to you guys,” Julien said. It sounds like good news for Bergeron’s long-term health, but his immediate availability to play some rough-and-tumble playoff hockey is something else. We’ll find out today if Bergeron can play in the Bruins’ do-or-die Game 6, maybe as early as the morning skate or as late as puck drop. If he can’t go, Julien may have to break up his lines. In Bergeron’s absence in Game 5, Julien moved Carl Soderberg up between Marchand and Jaromir Jagr, but wouldn’t commit to that trio yesterday. Chris Kelly could take that spot, as could Rich Peverley. Or Julien could look for new line configurations.
