PRAGUE — The Bruins and center Patrice Bergeron  have agreed to a three-year contract extension worth $15 million. The deal will carry an annual cap hit of $5 million, making him tied with Tim Thomas  for the team’s highest cap hit in the 2011-12 season (captain Zdeno Chara  remains unsigned following the coming season). RDS was the first to report the story.
Bergeron was set to become a free agent at season’s end, and after a very impressive preseason, the Bruins avoid the risk of seeing the 25-year-old center put together a career year and leave via free agency. Chara now becomes the team’s top priority regarding contracts, as he is in the final year of a five-year, $37.5 million deal signed back in 2006.
Bergeron’s career high for points in a season is 73, which he recorded in 2005-06, his second NHL  season. In 73 games last season, Bergeron picked up 52 points before adding 11 more in 13 postseason games.
Both Bergeron and general manager Peter Chiarelli are set to address the media today, so stick with the Big Bad Blog for everything from both sides following the Bruins’ noon skate (6 a.m. EST).
