Scott Hartnell can't damage his foot by playing. His return to game action will be determined by how much pain he can tolerate.
This is good news for Hartnell and the Flyers because he can't damage his foot further by playing. As long as Hartnell can take the pain he may return sooner than originally expected (4-6 weeks.) It has only been two weeks and his cast has already been removed, he could be back at the front end of that timetable.
