Overview

• Hamburger SV said on X that Katterbach rejoined first-team training on Monday as preparations began for the away match at RB Leipzig.
• Katterbach was sent to the U21s in late September for what the club framed as a short ‘thinking pause’ following concerns over his attitude.
• Polzin described the meeting as constructive and emphasized that team success takes priority while confirming the defender’s full reintegration.
• Reports note the 24-year-old made an engaged impression with the U21s, which supported the decision to offer a fresh start.
• Selection for upcoming matches remains open, with Polzin saying Katterbach must compete for a matchday spot after limited involvement since his long injury layoff.
