The Lions waived linebacker David Long on Tuesday, the team announced.
The Lions signed Long to the practice squad ahead of Week 12 after Alex Anzalone landed on injured reserve with an arm injury. A week later, they signed Long to the active roster.
He has appeared in five games with one start, seeing action on 70 defensive snaps and 58 on special teams. Long has seven tackles and a fumble recovery.
He began this season with the Dolphins, playing eight games with six starts.
The Lions also announced they re-signed wide receiver Maurice Alexander to the practice squad.
