Chisholm (back) underwent a CT scan Friday that revealed a stress fracture, Craig Mish of SportsGrid.com reports.

EDGE Analysis

Chisholm had progressed in his recovery in recent weeks, but he's expected to require approximately six additional weeks to recover following the results of the scan. While the 24-year-old initially appeared to be trending toward a return in late July or early August, he'll likely now be sidelined until at least early September. Joey Wendle should continue to see increased playing time at second base in Chisholm's absence until Jon Berti (groin) is back in action.
