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.
Unless he really collapses, I don't see him going anywhere. I've been very impressed with his composure and maturity. Once the regular season started, he was a different guy; it was like game on and almost as if he's been around for a long time.
