Bergenheim took part in Friday's morning skate in full gear, but Lightning coach Guy Boucher called him "doubtful" afterwards.
Bergenheim missed most of Game 4 with a lower-body injury. He skated briefly without equipment Wednesday prior to Game 6, but did not play, and Dana Tyrell took his spot in the lineup.
Tyrell and Blair Jones were in the Lightning lineup.
Before his injury, Bergenheim had nine postseason goals and was part of a potent line with Dominic Moore and Steve Downie.
