Anderson remains in the concussion protocol and won't practice Wednesday, Chris Brown of the Bills' official site reports.

Coach Sean McDermott already said Anderson -- if cleared -- would start in Week 10 against the Jets over turnover-happy Nathan Peterman. However, with the veteran still not practicing after first sustaining the head injury in Week 8, his availability for Sunday currently looks sketchy. The best hope for the Bills might be that rookie first-round pick Josh Allen (elbow) -- who is practicing on a limited basis Wednesday -- is able to get up to full speed by the weekend, though that's far from a certainty.
