What happened: Kevin Stefanski attributed Tua Tagovailoa's absence to a tight back. Michael Penix Jr. remains limited by a right knee injury and could wait another four weeks for 11-on-11 clearance.
Why it matters: Atlanta's quarterback competition cannot fully begin until Penix participates in team drills. The Falcons added Rush after opening camp with both contenders limited.
By the numbers: Penix is undergoing his third ACL rehabilitation in eight years.
What to watch: Tagovailoa's return to practice and Penix's progression toward 11-on-11 work will shape the camp competition.
