Brown (undisclosed) wasn't spotted during the open portion of Friday's practice, Jim Wyatt of the Titans' official site reports.
After being limited Wednesday for rest purposes, Brown returned to a full practice Thursday. Friday's final injury report will reveal whether the wideout's absence from the early portion of practice was maintenance-related or indicative of a setback that could result in a Week 8 injury designation approaching Sunday's game against the Colts.
