Boston Bruins center Patrice Bergeron is hospitalized under observation for a punctured lung, general manager Peter Chiarelli told reporters on Wednesday.
Chiarelli said the lung injury did not occur during a game but gave no additional details.
Bergeron was not at TD Garden with the rest of the team for its end-of-the-season departure on Wednesday.
A valiant Bergeron played 17 minutes, 45 seconds in Game 6 of the Stanley Cup Final on Monday night with a broken rib and torn rib cartilage. The Bruins lost 3-2 to the Chicago Blackhawks.
Bergeron was injured in Game 5 on Saturday night in Chicago during the second period and was taken to a local hospital for observation. But he returned to the team hotel that night and came home to Boston with the team the following morning.
In 42 games during the regular sason, Bergeron had 10 goals and 22 assists. He added nine goals and six assists in the playoffs.
