Dortch reverted to the Bills' practice squad Monday, per the NFL's transaction log.
Dortch was elevated to the active roster for a return role with the Bills' special-teams unit in Week 1. The wide receiver played 10 special-teams snaps, taking two punt returns for 10 yards and three kickoff returns for 82 yards en route to a 36-31 Bills victory. Dortch can only be elevated for two more regular-season games before he must be signed to the active roster to continue playing for Buffalo this season.
