UPDATE: Martin, Letang, and Potter are all to be in tonight's lineup against the Senators.
this morning, the Penguins recalled defensemen Corey Potter and Steve Wagner from their WB / S affiliate team; Matt Niskanen did not travel to Ottawa with the team due to the flu and I'm assuming that Kris Letang suffered an injury after the hit he took from Edmonton's Gilbert Brule during last Sunday's game against the Oilers; Letang did not practice and was to see a physician yesterday (but nothing has been confirmed as of right now).
INTERESTING NOTE: Paul Martin was not on the ice with the team at this morning's skate, so perhaps the second call-up is for Martin and not Letang (check back later for confirmation)
LINE COMBINATIONS (projected from today's skate)
the team did "rush drills" instead of skating with their lines according to today's Penguins Report
