Jimenez is dealing with minor left knee soreness, Daryl Van Schouwen of the Chicago Sun-Times reports.
The injury doesn't appear to be serious, but the White Sox are being cautious with their highly-touted outfield prospect. He hit Monday, and could be back in game action soon. The ailment is unlikely to have any impact on his ability to make the big-league roster, which he is very unlikely to do anyway, given that he's only played 18 games at the Double-A level.
