While Jackson remains in Detroit rehabbing with physical therapist Steve Scher, he isn't ready for baseball activities and won't do any until the Tigers return home and have their medical staff re-evaluate him Friday. That's also the first day Jackson will be eligible to come off the 15-day disabled list.
Any chance of having him back Friday with little or no work on the field now seems out of consideration.
"It's not going to be as soon as we'd hoped, obviously," manager Jim Leyland said of Jackson's return.
That's a tough break for the Tigers, who could use Jackson's glove and bat in center and leadoff, even if it means shifting hot-hitting Quintin Berry to another outfield spot or the bench. But it also delays the much-speculated roster decision on how to make room for Jackson if Berry's going to stick around.
