Ronald Darby (concussion) ruled out for Bills in Week 13

Buffalo Bills cornerback Ronald Darby (concussion) has been ruled out for Week 13.

What It Means:

Darby would have spent most of Sunday's game on Oakland Raiders wide receiver Michael Crabtree, so this is an improvement to Crabtree's matchup. The Bills will either trot out burnable Corey White at left corner, or move sixth-round rookie Kevon Seymour there. Either way, it's a great spot for Crabtree.

The Bills rank 17th in Defensive Passing Net Expected Points per play heading into Week 13.
