Status: Injury Reserve
Position: Tight End
Walker (ankle) is still donning a walking boot to protect his surgically-repaired right ankle, but the tight end is hopeful he'll be able to return from injured reserve at some point this season, Jim Wyatt of the Titans' official site reports. "In my mind, it's just to get healthy. But in the back of my mind, if I can get healthy earlier where I can come back and play, I'm going to do that," Walker said.
