Ihedigbo missed practice Wednesday due to an ankle injury.

While Ihedigbo isn't a full-fledged starter, he saw the most plays at strong safety in Week 12. With Aaron Williams and Robert Blanton out for the season, the Bills would be down to their fourth option if he can't go Sunday in Oakland. This is the first we've heard of the ailment, however, so there's a chance it's minor as the veteran continues to get himself in game shape after not having an NFL job the first nine weeks of the season.
