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.
