Vest has been diagnosed with a stress fracture in his right elbow, Chris McCosky of The Detroit News reports.
Vest will not require surgery, but he remains without a clear timetable for return after he was initially placed on the 15-day injured list due to right elbow inflammation July 1. It's been an ugly 2026 season for the right-hander, as he's posted a 6.08 ERA, 1.43 WHIP and 27:10 K:BB across 26.2 innings. His 3.41 FIP would suggest he's been extremely unlucky.
