Though he was initially expected to skate on his own prior to Tuesday's practice, MacDonald remained off the ice, Sam Carchidi of the Philadelphia Inquirer reports. Coach Craig Berube dismissed any notion that a setback might have prevented MacDonald from taking the ice, so it looks like the team will simply wait another day or two before letting the blueliner resuming skating. He's just past the three-week mark of the four-week projected timetable he was given when he suffered the injury in late October.
