Bruins general manager Peter Chiarelli, who last week placed center Patrice Bergeron on the long-term injured reserve list, yesterday told an all-sports radio station in Toronto the 22-year-old pivot could be finished for the season. "He is suffering from a serious concussion," Chiarelli told Don Landry and Gord Stellick, cohosts of Fan590's "The Morning Show." "And he could be out for the whole year." Bergeron, who sustained a Grade 3 concussion Oct. 27 when he was driven into the boards by the Flyers' Randy Jones, has been available to the media only once, for some 10 minutes, since the incident. Otherwise, according to club employees, he remains at his Boston condo, and receives treatment for his head and neck injuries with the team's medical personnel at the Garden or at the club's facility in Wilmington.
