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.
By the numbers: San Francisco is 3-1 this season with a three-game winning streak, averaging 24.8 points scored and 13.8 points allowed.
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.
