Sneed didn't participate in practice Wednesday due to a quadricep injury, Turron Davenport of ESPN.com reports.
Sneed logged 65 defensive snaps during the Titans' Week 6 loss to the Colts and finished the contest with eight tackles (seven solo). However, Sneed may have picked up the quad injury at some point along the way. He'll have two more chances to practice and avoid an injury tag ahead of Sunday's game against the Bills.
