Manager Walt Weiss said after Tuesday's game against the White Sox that Acuna is day-to-day with left hamstring tightness, Barrett Sallee of 680 The Fan Atlanta reports.
Acuna went on the injured list in early May due to a left hamstring strain, though Weiss noted that his latest injury doesn't seem to be as severe. The outfielder will undergo an MRI on Wednesday just in case. Eli White entered Tuesday's contest as Acuna's replacement and could be in line for additional starts if Acuna needs to miss another game or two.
