Johnson is just day-to-day with an undisclosed issue that occurred in Saturday's preseason game, the Tampa Bay Times reports.

EDGE Analysis

This is very fortunate news for the Lightning, as they lost both Johnson and Alex Killorn to undisclosed injuries Saturday, but both are just day-to-day. General Manager Steve Yzerman indicated that he's "hoping that everyone will be ready for Thursday" when the Lightning open their season against the Flyers, but that should sort itself out as the week progresses.
