The Patriots released veteran defensive end Cassius Marsh and signed defensive end Eric Lee off the Bills’ practice squad Tuesday.
Marsh, whom the Patriots acquired via trade from the Seahawks in September, has played in nine games this season and started one. Marsh had one sack, a forced fumble and 16 combined tackles as a Patriot.
Marsh only played two defensive snaps Sunday against the Raiders, and he failed to contain Raiders running back Marshawn Lynch on one of them. Lynch got outside for a 25-yard gain in the first half.
