Manager Mike Matheny said after Tuesday's win over Cleveland that Singer is dealing with a right "mid-arm" injury, and scans showed no damage to his elbow or shoulder, Joel Goldberg of Bally Sports Kansas City reports.
The 25-year-old was removed during the first inning of Tuesday's start with what was initially labeled right upper arm discomfort, but after some evaluation it appears he's avoided the most troublesome arm injuries. Singer didn't factor in the decision after giving up three runs on three hits and a walk over two-thirds of an inning. He lines up for one final turn through the rotation in the final game of the regular season Sunday against the Twins, though it's unclear whether the injury will cause his season to end a bit early.
