McAtamney reverted to the Giants' practice squad Monday, per the NFL's official transaction log.
McAtamney was elevated to the active roster prior to Sunday's 21-18 win over the Chargers, going 2-for-2 on field-goal attempts in the victory. With Graham Gano (groin) still sidelined for a few more weeks, McAtamney will likely get another shot with the Giants in the team's Week 5 matchup with the Saints.
