Versteeg is expected to miss about a month due to his left hand injury, Chris Kuc of the Chicago Tribune reports. The long-term nature of the injury prompted the team to promote top prospect Teuvo Teravainen from AHL Rockford, though it's likely Patrick Sharp that will get the first crack at filling in for Versteeg on the second line. With nine goals and 18 assists across 34 games, Versteeg had been in the midst of a resurgent year with the Blackhawks, but this latest setback may prevent him from delivering a 50-point season.
