Neither Jackson nor manager Jim Leyland had a timetable on when the center fielder will return. But after being evaluated Friday, Jackson reported he was pain free, and it's now all about how quickly he can get back into baseball shape without pushing it.
"I think it will be a true day-to-day thing now, because we kind of got that pain out of there, which was something that was there before," Jackson said. "It's just definitely feeling better, and I think that kind of getting a feel for it and how it feels during activity, I'll get a better idea."
Jackson was sent back to Detroit during the team's 10-game road trip and had been mostly resting and icing the area up until Thursday, when the 25-year-old said he did some conditioning to try to loosen up the muscle.
There were no ill effects, and now Jackson will continue to increase the workload.
"We're just going to get it loose and try to get back into some physical activity and see how it feels from there," he said.
