Indications are the Penguins do not expect Dustin Jeffrey back anytime soon, but the full extent of his injury…

is not yet known.
Dan Bylsma said during tonight’s media session, following Pittsburgh’s 1-0 shootout win vs the New Jersey Devils, that Jeffrey is scheduled to have an MRI on his right knee but the MRI has yet to happen.
The Penguins are waiting for the swelling to go down before conducting the MRI.
