Marsh (knee) was placed on injured reserve on December 10, and he ended the season with six tackles and a sack in four games.
Marsh averaged fewer than 10 snaps per game. He'll be an unrestricted free agent this offseason, but as he goes into his age-29 season, he's played on eight teams over his seven-year career, and it's unlikely he'll find enough of a role to become a solid IDP option.
