Chicago Blackhawks prospect Ryan Hartman will be out 1 to 3 weeks with a lower-body injury, reports Chris Block of ThirdManIn.com.
Block also notes that Kirill Gotovets is likely out until the playoffs, goaltender Mark Visentin is done for the season and Jay Harrison has a concussion.
Hartman, who was the Hawks' first-round pick in the 2013 NHL Draft, likely suffered the injury when he blocked a shot against the Lake Erie last Thursday, according to Block. The 21-year-old forward recorded his first NHL career point with an assist earlier this season with the Hawks during a three-game call up stint.
