Wilder had six carries for 21 yards in Friday's preseason game against Washington.
Even with Karlos Williams released, LeSean McCoy sitting out, and Mike Gillislee (concussion) unavailable, Wilder was only the fourth Buffalo running back to get work, trailing Reggie Bush, Jonathan Williams and Dan Herron. Unless Gillislee is still injured as the season approaches, Wilder appears unlikely to make the final roster.
