Ruhwedel (undisclosed) practiced in a red non-contact sweater Thursday, Peter Baugh of The Athletic reports.
Ruhwedel went into the boards hard during Tuesday's preseason win over the Devils, and while it's not yet clear what injury he's dealing with, he was limited during Thursday's practice session. Whether his ailment will hinder his availability for Friday's preseason finale against the Islanders remains to be seen.
