Jackson would like to do some low-intensity baseball work earlier, such as throwing. However, he doesn't have a timetable yet for a return to the active roster.
The Tigers have been getting by at Jackson's leadoff spot just fine in his absence thanks to a combination of Andy Dirks and Omar Infante. Dirks was 13-for-41 with two doubles and two home runs from the top spot before his first-inning single Friday night. Infante's three-hit game Thursday improved him to 6-for-14 in three games from the leadoff spot.
