While Jackson was limited in practice Friday, head coach Jay Gruden said it was a step in a positive direction, according to the report.
In his first season with Washington, Jackson has nine catches for 81 yards. He played the first six seasons of his career with the Eagles and amassed 356 catches, 6,117 yards and 39 total touchdowns.
Quarterback Robert Griffin III was also hurt against the Jaguars when he dislocated his ankle during the first quarter, and backup Kirk Cousins will start for Washington. Griffin will not be placed on injured reserve.
Washington plays the Eagles at 1 p.m. in Philadelphia.
