Danault went down with 1:37 left in the second period Saturday night. Chara, who has one of the hardest shots in the NHL, looked on in concern as trainers attended to Danault.
According to the CBC broadcast, the shot from Chara registered at 123.2 kilometers per hour, which converts to 76.5 mph.
Danault was moving and speaking to medical staff before he left the ice, receiving an ovation from the Bell Centre crowd. The team said he was taken to a hospital with a head injury for further examination.
After the game, Montreal coach Claude Julien said Danault is expected to remain in the hospital overnight and will be re-evaluated Sunday.
Both teams headed to the locker room after Danault got hurt, and the rest of the second period was played after intermission.
