Triple-A Durham placed Vernon (elbow) on its full-season injured list Friday.
The Rays initially shut Vernon down due to right elbow soreness back during spring training. The right-hander then went on a minor-league rehab assignment in May, making five appearances as a reliever, before going back on the shelf for good. His 2026 season ends with a 1.42 ERA, 0.79 WHIP and 8:2 K:BB across 6.1 innings in the Florida Complex League and for High-A Bowling Green.
