UNITED CENTER (CBS) Joel Quenneville didn’t exactly sound like a guy who had just completed half a season without a loss in regulation following the Blackhawks’ thrilling 3-2 come-from-behind win over the Avalanche Wednesday night.

That’s because he had just gotten done checking on the status of several players, including Patrick Sharp, who may have suffered a somewhat severe injury during the game.

“He might miss some time,” Quenneville conceded. “We’ll know more tomorrow.”

Sharp skated off the ice in the third period holding his shoulder, but there is some room for optimism as Quenneville said he doesn’t think it’s a season-ending injury.

Meanwhile, Marian Hossa was a late scratch with an upper-body injury after warming up before the game, but Quenneville said he was close to playing.

“Hopefully he’ll be ready for the next game,” Quenneville said, as the Blackhawks turn around and play the Avalanche again Friday night, but in Colorado.

Andrew Shaw also suffered an undisclosed injury during the game and missed the entire third period. He took an awkward hit late in the second period and was visibly shaken up on the bench.

After the game, Quenneville described Shaw’s injury as “not too bad”.

The Blackhawks could be shorthanded Friday night if either Hossa or Shaw can’t go. Forward Michael Frolik has missed the last two games with an illness and Quenneville said before Wednesday’s game that it’s “questionable” if he’ll even travel to Colorado with the team. The Blackhawks also sent forward Brandon Bollig down to Rockford earlier Wednesday.
