Tigers reliever Buck Farmer was forced to leave Wednesday's game with right forearm tightness, the team announced.
Farmer faced just three batters before the injury flared up in the seventh inning. He had allowed two hits and one home run before leaving. Farmer complained of tightness in his arm last week and had not pitched since Sept. 2.
"We had kind of avoided him because he had felt a tightness in his forearm, and had it treated for a number of days," Tigers manager Brad Ausmus said. "He said it felt good, and a couple days ago it felt normal. But apparently, he re-aggravated it."
