Ellis has begun range of motion exercises with his left ankle, which was twisted when he was taken out on a slide at second base by St. Louis' Tyler Greene last Friday night.
Ellis suffered trauma to the leg at the point of contact below his left knee, which resulted in the swelling and the need for a fasciotomy.
Ellis also is believed to have injured his left knee. He's on the disabled list and is expected to be sidelined a minimum of six weeks.
