Philadelphia, PA -- (Sports Network) - Philadelphia defenseman Braydon Coburn and Pittsburgh forward Gary Roberts missed Game 4s 4-2 win by Philadelphia in the Eastern Conference finals at the Wachovia Center.

Coburn took a puck to the face early in Game 2, and has not played since leaving the ice at Mellon Arena. Roberts, who has been in and out of the lineup this postseason, missed his second straight game due to a mild case of pneumonia.

The Penguins lead the series 3-1 with Game 5 set for Sunday afternoon in Pittsburgh.
