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.
You know what? We've played in some pretty special buildings along this playoff run so far. You start in Detroit, you go to Montreal, you come here … I think it's the first team to beat three Original Six teams to get to the Final if I'm not mistaken. That says how tough the road has been. Those are tough places to win.
