Letang (upper body) will be a game-time decision for Wednesday's clash with Calgary, Josh Yohe of The Athletic reports.
Letang is day-to-day after missing Tuesday's practice. The Penguins would be missing two integral defenders if Letang joins Erik Karlsson (lower body) on the shelf. Jack St. Ivany or Ilya Solovyov could slot into the lineup in a third-pairing role if Letang is unavailable.
