Carroll was outrighted to Triple-A Charlotte on Thursday, Scott Merkin of MLB.com reports.
Carroll will be removed from the 40-man roster, allowing the White Sox to add an additional arm in the rotation or bullpen. After a 2015 season where the right-hander produced a 3.44 ERA and 1.45 WHIP over 36.2 innings for the White Sox, the 31-year-old has regressed in 2016, spending the majority of the season with Triple-A Charlotte and logging a 5.27 ERA and 1.71 WHIP over 56.1 frames.
