Bayern Munich and Germany national team midfielder Lennart Karl has been ruled out of the 2026 FIFA World Cup after suffering a serious injury during a training session. The 18-year-old sustained torn muscle fibres in the front of his left thigh on Friday, June 5, 2026, while preparing for a warm-up match against the United States.
The Impact of Lennart Karl’s Injury
Lennart Karl’s absence represents a significant blow to the Germany squad ahead of the tournament. The attacking midfielder had established himself as a key prospect, contributing five goals and five assists across 26 Bundesliga appearances during the 2025/26 campaign. According to head coach Julian Nagelsmann, Karl’s “carefree attitude, creativity, pace and personality” made him an ideal fit for the team.
Nagelsmann confirmed the severity of the situation following medical examinations, stating, “It’s a huge shock for him and for all of us that he’ll miss the World Cup.” The injury occurred in Chicago, where the team had traveled to finalize their preparations for the upcoming tournament.
Squad Adjustments and Replacements
FIFA regulations permit national teams to replace injured players in their final squads up to 24 hours before their opening match. Following the diagnosis, Nagelsmann acted quickly to maintain the team’s depth. The coach selected RB Leipzig midfielder Assan Ouédraogo to take Karl’s place in the 26-man roster.
“In Assan, we’re now bringing in a player who, like Lenny, made an excellent start with us,” Nagelsmann noted regarding the roster change. Ouédraogo, who has also shown promise during the 2025/26 season, will join the squad as they transition into the final phase of their World Cup campaign.
