Irvin reverted to the Seahawks' practice squad Monday, per the NFL's official transaction log.
Irvin received the elevation to the active roster with the team dealing with multiple injuries throughout their linebacker corps. The veteran played on 24 defensive snaps and recorded two tackles against the Chargers on Sunday. He had just signed with team Oct. 11 and could earn a more regular role moving forward if the team continues to deal with injuries at linebacker.
