Locker will start Sunday's game against the Jets if Zach Mettenberger (shoulder, doubtful) is unavailable. Meanwhile, coach Ken Whisenhunt won't officially rule Mettenberger out for Sunday's game just yet, suggesting that the QB is week-to-week. At this stage though, the signs continue to point toward a scenario in which Locker likely ends up starting the Titans' final three game this season. We'll let you know if that assessment changes.
