Brown was listed as a limited participant in Wednesday's practice for non-injury reasons, Turron Davenport of ESPN.com reports.
The Titans have managed Brown's practice reps all season, though it's usually been attributed to a knee issue rather than just "rest." The new designation could be taken as a minor sign of progress, especially after Brown dealt with an illness last week on top of the lingering issues with his knees. He looked healthy while roasting the Chiefs for 133 yards and a touchdown in the Week 7 win, and he'll now take aim at the division-rival Colts on Sunday.
