"Andrew Brunette missed Friday's game with an undisclosed upper-body injury.

Brunette played only 2:30 in the first period of the Blackhawks' embarrassing 8-4 loss to the

Edmonton Oilers on Thursday.

General manager Stan Bowman said that there isn't a timeframe for his return and that the Hawks will have a better idea when they determine the extent of the injury.

"We're going to get a better evaluation when we get home," Bowman said. "We'll certainly have a better idea before the game in Denver. I don't know at this point if it's long term."

"I talked to him about it, and [there wasn't] a defining blow," coach Joel Quenneville said. "It might have been back-to-back games [being] something to it."

Michael Frolik took Brunette's spot on the fourth line."
