Sharp left Wednesday's 3-2 home win over the Avalanche with what looked like a shoulder injury after being checked along the boards by Colorado's Ryan O'Byrne. Coach Joel Quenneville said afterward Sharp might miss some time.
The Blackhawks also said Marian Hossa was travelling with the team after being scratched from Wednesday's game with an upper body injury, as was Andrew Shaw after taking an elbow to the chin from Paul Stastny.
Michael Frolik (illness) was expected to meet the team in Denver before Friday's game.
The Blackhawks also recalled forward Brandon Bollig from the Rockford IceHogs of the American Hockey League.
I have been blessed to play for 16 years in the NHL; it has been an amazing ride. I would like to thank the Tampa Bay Lightning and New York Rangers organizations and owners for providing me the opportunity to play the sport I love for so many years. I could have never played for so long or accomplished all that I have without the unwavering love and support from my wife, Heather, our three sons, Ryan, Lucas, and Mason, and my parents.
