Locker (right thumb) was limited at Thursday's practice, Jim Wyatt of the Tennessean reports. Per John Glennon of the Tennessean, coach Ken Whisenhunt indicated that Locker is progressing, but Glennon also notes that Charlie Whitehurst took the bulk of the team's QB snaps during the open portion of Thursday's practice. At this stage, Locker's Week 7 status remains unclear, though hopefully what he is able to do at Friday's practice will add some clarity to the situation in advance of Sunday's game against Washington.
