Chara confirmed the extent of the injury on Friday, when the team held its wrapup media availability two days after losing in Game 7 of the championship series to the St. Louis Blues.
Chara took a deflected puck off his face in the first period of Game 4 and returned, only to sit on the bench. But he was back for Game 5 and finished out the series.
The Blues won 4-1 on Wednesday night for their first NHL title.
The 42-year-old Chara says he learned this season that he can push his body further than he had previously thought.
