Lions running back Joique Bell (ankle) didn't practice Thursday.
Neither the nature nor the extent of the ankle injury are known, placing a cloud over Bell's Week 4 viability.
Consequently, owners should keep a watchful eye on his activity level as the weekend approaches to get a better picture of the breakdown of snaps within the Lions' backfield.
Through three games, Bell has handled 31 percent of the offensive snaps versus 43 percent for rookie Ameer Abdullah.
