(CBS) Just one day after assigning him to Rockford, the Blackhawks have recalled Brandon Bollig for Friday night’s game in Colorado.

Patrick Sharp did not travel with the team to Denver Thursday after suffering an apparent shoulder injury Wednesday night against the Avalanche. Marian Hossa and Andrew Shaw are also nursing injuries, but they did make the trip to Colorado and head coach Joel Quenneville expressed optimism after Wednesday’s win that they would be available Friday.

Meanwhile, Michael Frolik, who has been sick this week, will travel separately to Denver Friday.

With Sharp out and the status of three other forwards in doubt, the recall of Bollig was necessary. The Blackhawks were actually caught shorthanded Wednesday after assigning him to Rockford. When Hossa was a late scratch, the Hawks had to play defenseman Sheldon Brookbank on the wing with the fourth line.
