Kumerow (ankle) has been ruled out for Sunday's game against the Steelers, Ian Rapoport of NFL Network reports.

EDGE Analysis

Kumerow sustained a high-ankle sprain in the Bills' Week 3 loss to the Dolphins and will be unavailable for a second consecutive game. Jamison Crowder (ankle) will also be out, so it's possible that Khalil Shakir takes on an increased role for Buffalo.
