Titans running back Chris Johnson missed practice on Tuesday because of a sprained right ankle. He suffered the injury late in Tennessee's loss to Indianapolis on Sunday afternoon. "I think I should be good enough to go," Johnson said. "It's pretty sore -- I haven't ran on it and ... yesterday I was limping pretty bad. But I am doing much better." Despite a poor start, he's 70 yards from 1,000 for the season. "Any running back who runs for over 1,000 yards, it puts you up there in a group with elite running backs," Johnson said. "Even though I am not having the best of years, to go over 1,000 yards, that's something a lot of people thought probably wouldn't happen this year."
