DETROIT -- Austin Jackson had seven straight days of healthy, productive play since his return from the disabled list a week ago. His absence from Friday's starting lineup against the Red Sox was a reminder that the pulled left hamstring that sidelined him for a month remains a concern.
Manager Jim Leyland said he held out Jackson with soreness in his left leg. Jackson said it was in the same area where he pulled his hamstring in May.
"Same spot," Jackson said. "We just want to be cautious with it and not push it."
Jackson said the soreness didn't become an issue until Thursday. He was set to spend Friday getting treatment on it with the hope of returning to the lineup Saturday.
