"As part of Titans running back Chris Johnson's contract extension, he committed to spending more time at Baptist Sports Park.

His deal, which now runs through 2016, reduces by $250,000 in any year he doesn't take part in 30 of the team's 36 scheduled offseason workouts.

After spending the past two offseasons with a trainer in Florida, Johnson said he plans to be with his teammates in Nashville next summer.

The Titans, of course, are more worried about the present, and Sunday's season opener against the Jaguars. Their best player has had only a handful of practices since ending his 35-day holdout.

"When I go out there and start playing I'll know how much I can go and I'll know when I have to back down and things like that," Johnson said Wednesday. "I am used to the heat since I'd been working out in Florida, but not in a pad and helmets. We'll see when I get out there.""
