New York Islanders at Ottawa Senators

● Confirmed / Source-confirmed — The source explicitly labelled the lineup or starting goalie confirmed. This alone does not verify a coach's announcement. Skater lines and starting goalies are confirmed separately.

○ Projected — Expected lines that can still change before puck drop. A team projection is not confirmation for a specific game.

⊘ Out — The source lists the player as unavailable or outside the expected lineup. Check the injury or scratch label where supplied.

GTD — Game-time decision: the player's participation is uncertain.

? Unavailable — No current reported lineup is available, or its freshness cannot be verified. Older reports can be expanded inline where available; their original source dates are retained.

Observed usage — Last-game combinations show who played together and for how long. Their usage ranks do not confirm the next lineup or change reported F1/F2 assignments.
