The Jaguars waived Washington with an injury designation during the preseason and he later reverted tot their injured reserve list after clearing waivers. However, he was later cut loose a week into the regular season.
Jacksonville signed him to their practice squad close to a month ago.
In 2015, Washington appeared in four games and ran for eight yards on one carry to go along with no receptions or touchdowns.
