CHICAGO -- Chicago Blackhawks defenseman Michael Kostka left Tuesday's preseason game in the first period and did not return against the Detroit Red Wings after being illegally checked into the boards by Red Wings forward Teemu Pulkkinen.
Kostka laid face down on the ice for a few minutes and was attended to by the team's training staff. He was eventually able to skate off the ice under his power and went into the locker room.
Pulkkinen was given a game misconduct and a five-minute major boarding penalty at 2:16 of the first period.
After the game, the Blackhawks said Kostka suffered an upper-body injury.
"I thought [the hit] was very dangerous," coach Joel Quenneville said. "[Kostka's] not bad, but he couldn't play. We'll see a little bit better assessment [on Wednesday.]
"I think he's had a real good camp. We like what he brings to our team. He defends real well, real active in the attack, off the point. He wants the puck, make plays, sees plays. I think he's going to be useful."
The Blackhawks signed Kostka to a one-year deal in July. He was previously in the Toronto Maple Leafs' organization and spent time with the Maple Leafs and their AHL affiliate, the Toronto Marlies, last season. He played in 35 regular-season games and one playoff game with the Maple Leafs last season.
