Longoria (back) returned to Arizona on Thursday for more treatment, Nick Piecoro of the Arizona Republic reports.
Longoria traveled with the team to San Francisco, suggesting a return after the minimum 10-day requirement on the injured list, but he woke up Wednesday feeling stiff and was sent back to Arizona. The 37-year-old Longoria could still return at the 10-day minimum, but back issues are notoriously difficult to predict.
