Worth has played in only one rehab game since going out on assignment with Toledo. He aggravated his bruised left heel on Aug. 12, after which the Tigers recalled him from his rehab assignment. He has yet to heal sufficiently enough to return since.
With the Mud Hens' regular season ending on Labor Day, time is running out.
The 24-year-old Worth batted .255 in 39 games for the Tigers with five doubles, two home runs and eight RBIs.
