Haener reverted to the Giants' practice squad Monday, per the NFL's transaction log.
Haener was active for Sunday's 36-24 win versus the Cardinals, but his services were not needed, as veteran journeyman Jameis Winston started and finished the game at quarterback. Whether Haener is called up again in Week 5 might depend on how quickly recent trade acquisition J.J. McCarthy is able to familiarize himself with his new playbook.
