Sale will undergo an MRI on his left shoulder Friday, Ian Browne of MLB.com reports.
Sale was pulled from Thursday's game against Cincinnati due to shoulder soreness and experienced a drop in velocity during his start. The results of his MRI will provide an idea of how long he could be out for, but early signs are concerning. The 34-year-old southpaw held a 2.25 ERA and 0.75 WHIP across his last five starts entering Thursday.
