Braves manager Fredi Gonzalez indicated Friday that Jordan Walden is still experiencing discomfort in his back, and could be sidelined for at least another week. The organization still maintains that they're just being cautious and that it's nothing to be concerned about, but back injuries can tend to linger over the course of the season. Walden has been taking anti-inflammatory medication and completing rehab exercises to alleviate the problem and will be re-evaluated in a few days.
