Irvin reverted to the Seahawks' practice squad Monday, per the NFL's transaction log.
Irvin was elevated to the active roster for a second straight game but saw an increased role during Week 8 after Darrell Taylor (hip) left the game early. The veteran linebacker ended up playing 47 of the team's 65 defensive snaps and recorded two tackles, including one for loss. Regardless the severity of Taylor's injury, it appears Irvin will be a likely candidate for a third straight elevation in Week 9.
