What happened: Philadelphia running back Tank Bigsby requires surgery for a core muscle injury suffered Sunday, per RapSheet. The procedure will take place at the Vincera Institute associated with Dr. William C. Meyers.

Why it matters: Placement on injured reserve removes a backfield option and forces Philadelphia to redistribute carries. The absence tests running back depth and weekly rotation planning.

What to watch: Watch for Philadelphia to formalize the reserve move and clarify backfield roles.
