McCullers Jr. landed on the 15-day IL with right-hand soreness as the Astros push toward late-season goals. His return from a 2½-year rehab has been uneven, and a late-August move to the bullpen preceded this setback. With 15 games left, Houston faces a long evaluation window and possible rotation adjustments, while Colton Gordon emerges as a key depth piece. Fantasy managers should watch injury updates and bullpen roles for late-season streaming and potential holds in deep leagues.
