The Commanders signed Cowart to a contract Tuesday.
The Commanders hosted Cowart for a workout Monday, and the team liked what they saw out of the 2019 fifth-rounder, who spent most of last season on the Jets' injured reserve due to an ankle injury. Cowart last saw regular-season action in 2024 with the Bears, when he logged 26 tackles (14 solo), including 2.5 sacks, across 15 games.
