While Patrick Sharp didn't make the trip to Denver for Friday's rematch with the Avalanche, Marian Hossa, Andrew Shaw and Steve Montador were on the Blackhawks' team charter that left on Thursday.
Sharp was injured in the third period when he was checked hard into the glass by Avs defenseman Ryan O'Byrne and left the ice holding his left shoulder. NBC Sports Network reported late Thursday that Sharp could miss three weeks the injury.
Hawks coach Joel Quenneville called it an upper-body injury, saying Sharp would "miss some time." Quenneville will update the media on Sharp's condition following Friday's morning skate in Denver.
Michael Frolik, who has missed the last two games with the flu, wasn't on the charter but will meet the team in Colorado.
Hossa was a late scratch Wednesday with an upper-body injury. He took the pregame warmup but decided he couldn't go.
Shaw was hurt in the second period when he took an elbow from Paul Stastny in the head.
Winger Brandon Bollig was recalled from Rockford, one day after being sent down.
