UPDATE: The Penguins posted new video of Sidney Crosby's rehab workout from Monday (courtesy Penguins/NHL.com):

Sidney Crosby skated again before Sunday's game between the Penguins and Rangers (New York won 5-2), but there is still no timetable for his return.

The video below (courtesy of NHL.com) shows the Pittsburgh captain participating in skating and puck drills Sunday morning. Crosby (concussion) has been out since Jan. 6.
