According to reports out of the Rangers' practice facility in Greenburgh, N.Y., defenseman Marc Staal is not taking part in the team's optional practice Thursday.
Staal, 26, did not play Wednesday night, just two days after making his anticipated return to the lineup for Game 3.
Staal missed two months after a harrowing injury to his right eye. He skated with the team for several weeks before making his comeback, but was forced to deal with blurry vision as a lingering effect from taking Kimmo Timonen's shot to the eye during a game on March 5.
After Game 3, Staal alluded to some issues with his eye that had cropped up the previous week; it is unclear whether those issues resurfaced prior to Game 4.
Staal has previously said he did not want to play and jeopardize the team if he wasn't feeling fully comfortable on the ice and able to contribute.
