Jake Locker (ribs) practiced fully again Friday and is listed as probable for Week 15. Locker's injury won't affect his availability for Sunday's game, but Matt Hasselbeck's (calf) ability to practice on both Thursday and Friday means Locker will be the Titans' backup quarterback in Indianapolis. Barring an unforeseen change in the Titans' Week 15 plans, Locker is no longer a two-QB league option.
