This injury will not require surgery.
"It's unfortunate that (Carcillo) finally gets back in and he had 10 great minutes with his ice time (Saturday)," Blackhawks head coach Joel Quenneville told the Tribune. "But keep your spirits up and work through it and get excited to come back again.
"He knows the process of working in that rehab area and the commitment needed to get his game back where it was. It will be a process but we'll look forward to getting him back."
In just 28 games with the Hawks last season, Carcillo collected two goals and nine assists for 11 points, and 82 penalty minutes.
To replace Carcillo in the lineup last night, the Blackhawks had forward Brandon Saad playing on the club's first line with Jonathan Toews and Marian Hossa.
