Walker (undisclosed) won't suit up for Saturday's preseason contest against the Buccaneers, Terry McCormick of TitanInsider.com reports.
Walker left Thursday's practice with an evident limp at the conclusion of a catch. The severity and nature of the injury are unknown, but the Titans will hold out their starting tight end in this exhibition. Expect Jonnu Smith to get a healthy dose of reps with the first-team offense during Walker's recovery.
