What happened: The deal begins on the practice squad while Cooks gets up to speed for game action. It is year 13 for the former first-round pick from Oregon State.
Why it matters: San Francisco adds veteran depth with receiver injuries mounting. The move gives the offense an experienced route-runner without using an active roster spot.
By the numbers: Needs 189 yards for 10,000 career receiving yards. Entering 13th NFL season.
What to watch: Watch for elevation to the active roster once ready.
