Justin Diehl

Out until late September

Diehl sustained a muscle injury in the front of his thigh during team training and will be unable to participate in training or match play at least until the international break at the end of September 2026, the club announced.

Analysis: Diehl's latest setback continues a frustrating pattern for the young forward, who didn't feature in the Bundesliga last season and instead played primarily for Stuttgart's U21 side in the 3. Liga while working through a string of injury issues. This new thigh muscle injury will keep him out until at least the end of September, further delaying any path back into first-team contention.
