Green notched eight carries for 63 yards and four catches for 87 yards and a touchdown in Thursday's preseason finale against Buffalo.
The undrafted rookie out of Cincinnati is hoping the Lions keep five running backs, as Ameer Abdullah, Theo Riddick, Dwayne Washington and Zach Zenner (undisclosed) are all seemingly locks to make the roster. Despite his impressive showing in Thursday's exhibition, Green seems more likely to land on the Lions' practice squad.
