What happened: Cooper Rush has started 16 games over eight seasons and would move into the starting role if Tua Tagovailoa cannot play Sunday against the Pittsburgh Steelers. Tagovailoa was limited Thursday with an oblique strain and is considered day-to-day.
Why it matters: The Falcons' Week 1 quarterback plan remains conditional heading into their opener. A change would elevate Rush from backup to starter against Pittsburgh.
By the numbers: Rush: 16 career starts over eight seasons.
What to watch: Tagovailoa's next practice status and Sunday's inactive list will determine whether Rush starts.
