The Commanders placed Davidson on the reserve/retired list Saturday.
Davidson was a fifth-round selection of the Giants in the 2022 NFL Draft. He appeared in 47 regular-season games (four starts) across four years with the Giants and logged 49 tackles (26 solo), including 2.5 sacks, two fumble recoveries and three pass defenses. Davidson signed a one-year contract with the Commanders in March, but the Arizona State product will hang up his cleats instead.
