Walker (knee) caught 4-of-6 targets for 54 yards in Thursday's 21-13 loss to the Jaguars. Walker, who was listed as questionable on the final injury report, did not appear to be bothered by his knee. His target total fell somewhat below expectations, given that Charlie Whitehurst attempted 35 passes. One of Walker's targets came in the end zone, and while the tight end did a nice job to get open, Whitehurst misfired on the throw. The Titans face the Colts in Week 17, and Whitehurst will probably get another start, as Zach Mettenberger (shoulder) seems unlikely to play.
