The Atlanta Falcons have ruled out quarterback Tua Tagovailoa for Week 1 against the Pittsburgh Steelers after he suffered an oblique injury during Thursday practice, per ESPN's Adam Schefter. Cooper Rush will start the season opener in his place.

One outlet also reported that Michael Penix Jr. has been ruled out for Week 1, though this detail did not appear consistently across all reporting. Head coach Kevin Stefanski announced the decisions, per one account, and indicated uncertainty about Tagovailoa's return timeline.

Tagovailoa was named the Falcons' starting quarterback ahead of the season after signing with Atlanta to compete with Penix Jr. for the position.
