Spears (ankle) returned to practice Thursday, Turron Davenport of ESPN.com reports.
Spears didn't practice Wednesday, but his return to the field a day later isn't surprising, given his previous assertion that he'd be available Sunday against the Packers, per John Glennon of NashvillePost.com. That notion would be further solidified if Spears is listed as a full participant in Thursday's session.
