Chicago Blackhawks forward Ryan Hartman will "miss some time" with a lower-body injury, according to coach Joel Quenneville.
Hartman was in the lineup Friday versus the Nashville Predators but did not return after the first period. Early on, he drew an assist on Marcus Kruger's goal to open the scoring.
Hartman, 22, is expected to miss "more than a couple of games," according to Quenneville.
