What happened: Cleveland announced Sunday that safety Grant Delpit is undergoing a concussion evaluation. Delpit previously appeared on the Browns' Sept. 26 injury report as questionable alongside cornerback Tyson Campbell.

Why it matters: Delpit returned to practice in late July after ending a training camp hold-in and serves as a centerpiece of Cleveland's defensive backfield. Any absence during regular-season action forces the Browns to adjust their safety rotations and coverage packages.

What to watch: Monitoring continues for an official game-status designation from Cleveland following the completion of the medical evaluation.
