Loftin is out of the lineup for Sunday's game against the White Sox due to a groin contusion, Anne Rogers of MLB.com reports.
During Saturday's 2-1 loss, Loftin went 0-for-3 with a strikeout before being lifted in the bottom of the ninth inning after being struck by a throw to third base from Daniel Lynch. Loftin indicated he's feeling much better Sunday and will be available off the bench, so the 27-year-old would appear to have a good chance at returning to the starting nine Tuesday versus the Rays.
