Ansah had not been practicing with the team while recovering from offseason shoulder surgery. On the Lions' first depth chart, he is still listed as the starter at defensive end, alongside fellow former first-round picks Nick Fairley and Ndamukong Suh.
The Lions' next preseason game is Friday, Aug. 15 at Oakland.
