Boston Bruins centre Patrice Bergeron suffered a concussion in Tuesday's game against the Ottawa Senators and the timetable for his return is unknown.
Bergeron was injured in the second period after getting tangled up with Senators forward Colin Greening in front of the Bruins net. According to Chiarelli, Bergeron was hit below the ear. In addition to having the concussion, Bergeron is also experiencing neck soreness, Chiarelli revealed.
"I don't know when you'll see him again. Well, you'll see him again but I don't think you'll see him tomorrow. He sounded good, and I told him that we'll work together at getting him back," Chiarelli said.
This is the fourth concussion Bergeron has suffered in his career. His concussion troubles began Oct. 27, 2007 against the Philadelphia Flyers when defenceman Randy Jones hit Bergeron from behind and into the end wall. He missed the rest of the season and the Stanley Cup Playoffs with a Grade 3 concussion.
Bergeron returned to health the next season but missed 15 games after he collided with Carolina Hurricanes defenceman Dennis Seidenberg and was diagnosed with a less severe concussion.
Head troubles struck Bergeron again during the Bruins' run to the 2011 Stanley Cup championship, and Bergeron was forced to miss the celebration as the Bruins completed a second-round four-game sweep of Philadelphia. Claude Giroux knocked out Bergeron with a concussion-causing hit. Bergeron missed the first two games of the Eastern Conference Finals against the Tampa Bay Lightning.
