CHICAGO -- White Sox right fielder Avisail Garcia left Thursday's 6-3 loss to the Royals before the start of the third inning because of a stiff lower back.
Garcia lined out to first baseman Eric Hosmer to start the bottom of the second, but was replaced by Moises Sierra in right field to start the top of the third. Garcia missed four months with a torn labrum and avulsion fracture in his left shoulder, sustained while diving head-first for a fly ball on April 9 in Colorado. He has finished the season strong, though, with a .273 average, three homers and 13 RBIs in September.
"It looked like he took a couple of weird swings in the first inning and then he hit a line drive to Hosmer," said White Sox manager Robin Ventura. "It was hit pretty sharp and he didn't get out of the box too good, so I started talking to him after. It's better not to take any chances."
Ventura does not expect Garcia to play Friday.
