From the Rangers website:
Following an injury suffered in last night’s game vs. Philadelphia, Rangers alternate captain Marc Staal was examined today in New York by Dr. Mark Fromer, ophthalmologist, and Dr. Mendel Markowitz, maxillofacial surgeon.
The injury has improved significantly and both doctors are optimistic that Marc will make a full recovery.
Staal will be sidelined indefinitely.
Excellent news for the young, talented d-man.
