Griffin, who had been wearing a hard cast in the immediate aftermath of the injury and later a walking boot, wore cleats on both feet and participated in agility and stretching drills, according to Mike Jones of The Washington Post. Griffin did not participate in any position drills, Jones said, but "appeared to jog fairly well."
Washington decided not to place Griffin on season-ending injured reserve after an MRI revealed no fracture in the ankle.
Washington has declined to give a timetable for Griffin's return, which occurred on Sept. 14. ProFootballTalk reported the team hoped Griffin would miss four or five weeks, while the Post cited several surgeons who said the best case scenario would be a six- to eight-week recovery.
Kirk Cousins has started in place of Griffin in Washington's last two games, both Washington losses.
Washington is 1-3 and plays the Seahawks on Monday night.
