The Red Sox placed Garcia on the 15-day injured list Tuesday with right elbow inflammation, Chris Cotillo of MassLive.com reports.
Since joining the Red Sox in late July, Garcia has allowed 13 earned runs in just 11.1 innings out of the bullpen, and he'll now be held out of action for at least the next 15 days. Josh Winckowski was recalled from Triple-A Worcester to fill the open roster spot.
