Blackhawks winger Patrick Kane is doubtful for Friday's game against the Red Wings, according to coach Joel Quenneville. Kane practiced with his teammates for several minutes on Thursday before leaving the ice. "[It's] part of the process," Quenneville said. "He might need a day off. He was on there for two days in a row and today he may have aggravated it, but I don't think it's where it's a step in the wrong direction."
