The Jaguars will be without wide receiver Mike Sims-Walker on Sunday against the Titans because of a high right ankle sprain. Sims-Walker, who sprained his ankle three weeks ago in the second quarter against the Texans, will remain in Jacksonville getting treatment. "It's hard to go out there when you're not healthy, 100 percent, and you're playing against some of the best guys in the world," Sims-Walker said. "Pro Bowlers and whoever you're going against. I tried to gut it out, man, but I could tell it's just not me."
