The Pittsburgh Penguins might have another key member of their defense out for Game 6 against the New York Rangers.

Defensemen Brooks Orpik and Olli Maatta did not take part in the team’s morning skate. Orpik has played in just one game in the series, but Maatta has been a steady producer on the second pairing with Matt Niskanen.

The Pens have gotten around Orpik’s absence with Robert Bortuzzo, but if Maatta can’t play it’ll be Deryk Engelland who will likely step into his place. Engelland hasn’t played since April 12 against Philadelphia and in 56 games this season he had six goals and 12 points.
