Garcia was placed on the 7-day injured list Thursday with an undisclosed injury, Colin Beazley of the Pittsburgh Post-Gazette reports.
The Pirates demoted Garcia to Triple-A Indianapolis on Aug. 14 after he had been up with the big club since July 29. The 23-year-old got three hits with an RBI and no walks across 11 plate appearances in the three games he appeared in after being optioned.
