Neither coach Joel Quenneville nor assistant general manager of hockey operations Stan Bowman would elaborate on the severity of Seabrook's condition, or what tests he has undergone to check for a possible concussion.

The Blackhawks face the Los Angeles Kings on Thursday night.

"He's got an upper-body injury right now. We'll say day to day right now, but we don't know more than that," Quenneville said Thursday.

After Wednesday's game, Quenneville called Wisniewski's hit as bad as they come.

"You hit a guy without the puck, you could kill a guy," Quenneville said. "It's the most dangerous hit in the history of the game, all right.

" ... He tried to hurt him," Quenneville added. "If that's not intent, that's as bad a hit as you could ever have in the game."

In a conference call Thursday, Ducks general manager Bob Murray took offense to Quenneville's assertion.

"I played in Chicago for a long time, I lived in the city of Chicago, it used to be a black-and-blue town, it didn't have whiners," Murray said. "I strongly suggest Joel worries about his goaltending and stops trying to run the National Hockey League. He should worry about coaching."

Wednesday was the second game in a row that the Blackhawks lost a valuable member of their defense to a big hit.

On Sunday against Washington, three-time All-Star defenseman Brian Campbell was driven into the end boards from behind by NHL scoring leader and two-time MVP Alex Ovechkin.

Campbell will miss seven to eight weeks because of the fractured collar bone and broken rib he sustained. Ovechkin received a two-game suspension for the play.

"I'm not comparing the two and the quantity of games. That's not for me to decide," Quenneville said. "I'm not so worried about that. I'm worried about Seebs. That's what I'm worried about. We don't have him tonight."

Bowman also had little to say about the length of Wisniewski's suspension compared to Ovechkin's, saying: "The league's job is to weigh all the factors, and they have a lot more experience in that stuff than I do. So you have to assume they did their homework and they came to that decision for the right reason.

"The league obviously looked at it and they think that's the right number. But we're just going to move forward. We're not going to focus on that anymore. We're more worried about Seabrook than Wisniewski."

Wisniewski, who began his career with the Blackhawks before getting traded to the Ducks in March 2009, also was suspended for two games Oct. 31, 2009, and is considered a repeat offender under the terms of the Collective Bargaining Agreement. He will forfeit $268,292 in salary.

"Mr. Wisniewski delivered a retaliatory hit to the head of an opponent who never had possession of the puck," said Colin Campbell, NHL Senior Executive Vice President of Hockey Operations. "The fact that Mr. Wisniewski is a repeat offender also entered into this decision."

Wisniewski will be eligible to return April 3 at Los Angeles.
