Zuccarello (undisclosed) left Friday's Game 5 against the Penguins in the first period due to injury, Pat Leonard of the New York Daily News reports.

Analysis:

Zuccarello was forced from Friday's contest after taking a puck directly to the head from a slap shot. The nature of the injury is unclear at this point in time, but any time a player takes a puck up high is cause for concern. It remains to be seen if Zuccarello will be able to return.
