Stamkos, 31, didn't play against the Florida Panthers on Thursday due to a lower-body injury and missed practice Friday. He's the only Lightning player currently on the list.
The 6-foot-1 pivot opened up about the situation later Friday.
Stamkos leads the Lightning with seven goals and ranks second with 14 points through 11 games.
Tampa Bay is slated for a rematch with the Panthers on Saturday before the teams close out their three-game set Monday.
