Coach Ken Whisenhunt indicated Monday that Locker's (right thumb) Week 7 status remains unclear, Jim Wyatt of the Tennessean reports. While Whisenhunt reiterated that Locker remains the Titans' starter when healthy, at this stage the QB's status for Sunday's game against Washington is uncertain. In place of Locker in Week 6, Charlie Whitehurst threw for 233 yards in the team's 16-14 win over the Jaguars.
