Pittsburgh won 4-2 and leads the best-of-7 series 3-1 with Game 5 on Friday at Consol Energy Center (7 p.m. ET; CBC, RDS, NBCSN).
Orpik's absence reduced Pittsburgh to five defensemen. Paul Martin played 30:05, and Kris Letang played 27:56.
Orpik was making his first appearance in six games after sustaining an undisclosed injury in the Eastern Conference First Round series against the Columbus Blue Jackets. He played nine shifts in the first period, but the last one lasted seven seconds, ending at 18:23.
The old saying in hockey is 'weather the storm.' I put the notion in their heads that we don't want to weather the storm, we want to push just as hard and matched their work ethic. I thought our guys exceeded that in the first period.
