Mahle has been diagnosed with an impingement to the back of his right elbow, Do-Hyoung Park of MLB.com reports.
Mahle exited Thursday's start against the Royals with the injury but didn't have any imaging done, and the issue will be treated with anti-inflammatories. It's possible he could even make his next start if the symptoms clear up in a few days. Realistically though, Mahle will probably be pushed back, with a trip to the injured list also possible.
