Hall reverted to the Falcons' practice squad Monday, per the NFL's official transaction log.
Hall was elevated to Atlanta's active roster for Sunday's win over the Lions with Tajae Sharpe (foot) sidelined. Even so, he played only five offensive snaps while also recording one catch on one target for 10 yards. If Sharpe remains sidelined, it's possible that Hall will be promoted again for a Week 17 matchup against the Bills.
