According to Clarence Hill Jr., the Cowboys are placing LB Justin Durant on the non-football injury list and DT Richard Ash on the physically unable to perform list.
Durant, 31, is a former second-round pick of the Jaguars back in 2007. He spent four years in Jacksonville before signing on with the Lions in 2011. Durant later played two years for the Cowboys before signing three-year, $10.8 million contract with the Falcons.
Atlanta elected to cut Durant loose back in February of last year and he eventually signed a one-year contract with the Cowboys.
