The Detroit Tigers will be without their ace for the foreseeable future, as Tarik Skubal is set to undergo surgery on his left elbow.

Manager A.J. Hinch announced before Monday night's matchup against the Boston Red Sox that an examination revealed loose bodies in the two-time reigning AL Cy Young winner's elbow. Skubal, 29, has been placed on the injured list with no specific timeline for his return.

The injury scare came during the seventh inning of his last start on April 29 against the Atlanta Braves. Skubal was seen calling time, shaking his left arm, and rubbing his elbow as Hinch and assistant athletic trainer Kelly Rhoades rushed out of the dugout. After a brief conversation and just one warmup pitch, the left-hander stayed in the game—but the damage had already been done.

For a Tigers team that has leaned heavily on its pitching staff, losing Skubal is a significant blow. The 29-year-old has been the cornerstone of Detroit's rotation, and his absence will test the depth of a club with postseason aspirations. Fans will be eagerly watching for updates as the team navigates this critical stretch without its most dominant arm.
