Ball returned to practice Monday in a limited role. He missed the first week-plus of training camp with an ankle injury sustained during minicamp in June.
Ball says he "hadn't put full pads on since the end of last year, but getting the feel of everything, it felt good. I don't feel like I'm a step behind. I'm ready to keep going and moving forward."
The seventh-year pro started 15 games for Jacksonville last season, finishing with 47 tackles, a team-high 14 passes defensed and two interceptions.
With Ball back, the Jaguars have one player remaining on the PUP list. Linebacker Dekoda Watson (groin) should return in a few weeks.
