What happened: San Francisco paired the move with an injured reserve transaction at wide receiver to open a roster spot. The change adds defensive-line depth to the active roster ahead of the club's next game.

Why it matters: The move formalizes the climb for Okoronkwo after San Francisco worked him out in August. It also trims the receiver room by one active-roster slot, shifting depth toward the front.

What to watch: The next availability report will show how quickly Okoronkwo is folded into the rotation and how San Francisco reallocates receiver depth after the IR move.
