Smith (ankle) was a limited participant in Wednesday's practice, Turron Davenport of ESPN.com reports.
Smith is nursing a sprained ankle, which he sustained during Sunday's win over the Texans. The Titans reportedly consider Smith's injury minor, but his status for the Week 7 matchup with Houston will remain in question as long as he's unable to take on full practice reps. If Smith is sidelined Week 7, more work would open up for Anthony Firkser, who broke out with 113 yards and a touchdown versus Houston.
