Anderson (concussion) is still listed as a limited participant for Thursday's practice, Chris Brown of the Bills' official site reports.
Anderson suffered the concussion all the way back in Week 8, so it's a bit surprising he's not back in full action at this stage. However, as the No. 3 quarterback for a team that wants to get rookie Josh Allen all the playing time he can get no matter how he plays, it's highly unlikely Anderson sees the field again in 2018.
