Murphy had 13 points (five goals, eight assists) in 52 games last season. The defenseman missed the first 30 games last season with a back injury; he returned on Dec. 9 against the Montreal Canadiens. There is no timetable for his return, but Blackhawks coach Jeremy Colliton said the injury is not serious.
De Haan is fully recovered from shoulder surgery he had in May, but the defenseman also has a groin injury. He is close to returning, Colliton said.
"We still have a couple of days to figure it out," Colliton said. "We definitely don't want to play him before he's ready. That being said, if he's 100 percent, there's no reason to hold him out. We do have [defenseman Dennis] Gilbert here if necessary, but we'll see how it plays out."
Chicago acquired de Haan and forward Aleksi Saarela in a trade with the Carolina Hurricanes for goalie Anton Forsberg and defenseman Gustav Forsling on June 25. De Haan had 14 points (one goal, 13 assists) in 74 games with the Hurricanes last season.
