As bad it looked it didn’t turn out worse.

Red Wings defenseman Niklas Kronwall suffered a mild concussion after being slammed into the end boards by Colorado Avalanche forward Cody McLeod on Thursday.

Red Wings general manager Ken Holland said Friday that Kronwall is day-to-day.

“He’s not ruled out yet” Holland said of tonight’s game in Phoenix.

Kronwall was hurt at 2 minutes 13 seconds of the second period of Thursday’s victory. He was skating back to retrieve a puck when McLeod checked Kronwall into the boards. Kronwall’s head hit the area between the glass and dasherboards.

Replays showed Kronwall did put himself slightly into a vulnerable position by turning. But McLeod also had a responsibility on the play.

“When you carry a lot of speed in on the forecheck you have to be responsible for what you’re doing” Red Wings forward Daniel Alfredsson said. “Especially when you carry a lot of speed.”

Kronwall was on the ice for a short time and eventually carried off on a stretcher.

“Just awful” Alfredsson said. “You’re always worried about the neck and back and but we saw him move and tried to get himself up. That’s a good sign.”

Kronwall was answering the doctor’s questions alert and responsive shortly afterward in the Red Wings locker room.
