The 30-year-old winger, a key spark in Bayern's attacking arsenal this season, felt a minor twinge in his adductor during Friday's final training session, forcing him to the sidelines as a precaution.
With the squad already stretched by other absences, his withdrawal tested Bayern's depth, yet they held firm to extend their Bundesliga lead.
Bayern's board member for sport, Max Eberl, moved quickly to calm nerves in an interview with Bild. "It’s not too serious with Serge," Eberl said. "In the final training session on Friday, he felt a slight twinge in his adductor, a minor pain.
"Nothing is damaged, nothing dramatic. So he should be available again relatively quickly."
Gnabry echoed the optimism post-match, describing his condition as "good" when pressed on his fitness. For a side that thrives on fluid transitions and explosive counters, hallmarks of Vincent Kompany's early tenure at the helm, this news couldn't come at a better time.

If Gnabry slots in seamlessly, expect Bayern's front line to regain that lethal edge that has defined their dominance in recent years.
