Hentges has been pulled off his rehab assignment due to renewed soreness in his left shoulder, Zack Meisel of The Athletic reports.
Hentges had made four rehab appearances, but in his last one he allowed three runs without recording an out. The left-hander will be re-examined by doctors to determine the next steps in his recovery, but it sounds as if the Guardians aren't expecting the reliever to be available any time soon. Hentges has been on the 15-day injured list since July 12.
