What happened: Miami placed inside linebacker Ronnie Harrison Jr. on injured reserve and signed inside linebacker Liam Anderson from the practice squad to the active roster. The club also elevated edge rushers Clelin Ferrell and Max Llewellyn for Sunday against San Francisco.

Why it matters: The shuffle remakes Miami's front seven on game weekend and opens a larger role for Anderson with Harrison unavailable. It also adds edge depth after <a href='https://wire.report/article/dolphins-rule-out-chop-robinson-for-sunday-against-49ers-2026-09-19'>Miami ruled out Chop Robinson for Sunday against the 49ers</a>, putting more game-day weight on Ferrell and Llewellyn.

What to watch: Sunday's inactive list and snap counts will show whether Anderson is needed for defensive work or mostly special teams, and how much edge volume Ferrell and Llewellyn absorb.
