Jackson left Sunday's game in the eighth inning because of his left foot.
White Sox manager Robin Ventura said before Monday's series opener against the New York Mets that he doesn't think Jackson's injury at this point merits a move to the disabled list. He adds that the team does not "necessarily want to lose him for two weeks right away."
Shuck was batting fifth and playing center field Monday. He was 0 for 9 with the White Sox before he was sent down April 18 when Chicago needed to add a pitcher. He is hitting .299 at Charlotte with two homers and 17 RBIs.
Kahnle is 0-1 with a 2.70 ERA in four games over three stints with Chicago this season.
