Detroit defenseman Niklas Kronwall was carried off the ice on a stretcher after being rammed into the boards on Thursday night against the Colorado Avalanche.
Kronwall was trying to gather the puck in the corner early in the opening period when he was hit by Avalanche forward Cody McLeod. Kronwall's helmet flew off as he fell to the ice.
According to the Red Wings, the defenseman has suffered a concussion and had been treated at the rink.
"Kronwall has a concussion; cuts to the ear but he's moving all extremities, being treating in locker room. #WinForNik," the team tweeted.
Several teammates gathered around Kronwall as the dependable defenseman was strapped to the stretcher. Kronwall tossed away one of his gloves.
McLeod received a 5-minute penalty for boarding and a game misconduct.
Kronwall has one goal and five assists in seven games this season for the Red Wings.
