Burger was lifted from Wednesday's contest against Minnesota in the fifth inning due to an apparent side injury, Daryl Van Schouwen of the Chicago Sun-Times reports.
Burger appeared to wince and grab at his left side after swinging and missing at a pitch in the fourth inning. More details will likely come after Wednesday's game, but the 27-year-old infielder should be considered day-to-day until more is known. Hanser Alberto came in to replace Burger at third base.
