Polanco was put on the disabled list on Aug. 16 with a separated left shoulder after making a tumbling catch five weeks ago at Boston. He was expected to be out four to six weeks.

If Polanco is out for the season - and not just reacting emotionally to a setback - it would be a blow to the Tigers, who have lost 24 of 37 and start a three-game series today at Chicago.

Lee has family emergency: Cubs first baseman Derrek Lee could miss the rest of the season because his 3-year-old daughter, Jada, has an illness.

"My daughter's lost some vision in one eye and we'll find out more at a later time; we have to go through some more tests," Lee said in a statement. "Right now we just ask for everyone's prayers."

Lee, 31, has played in 49 games, hitting .287 with eight homers and 30 RBI. He missed 58 games with a broken wrist, then went on the DL again in late July with inflammation in the wrist.
