What happened: San Francisco 49ers defensive end Nick Bosa and New Orleans Saints wide receiver Jordyn Tyson returned to practice on Thursday. Bosa was limited during the session as he works back from calf and knee issues. Detroit Lions linebacker Jack Campbell also reported progress in his rehabilitation, maintaining full lower-body movement.

Why it matters: The 49ers need defensive reinforcement after dropping a 29-20 decision to the Falcons in their last outing. New Orleans is looking to activate Tyson from injured reserve to support an offense that scored just 10 points against Pittsburgh. Detroit holds a winning record in a tight division race following a 19-15 victory over Minnesota, making Campbell's defensive presence crucial down the stretch.

What to watch: Final injury designations will determine whether Bosa is cleared to play this weekend, while New Orleans continues evaluating Tyson's practice window.
