Bayern Munich goalie and captain Manuel Neuer has suffered a setback in his return from a calf injury, the German club said in a statement on Saturday.
Neuer has been out since tearing his calf muscle while celebrating a goal in Bayern's Champions League last 16 first leg win over Bayer Leverkusen in early March.
The 38-year-old had returned to training with the ball in recent days but reinjured the calf muscle in training this weekend.
Bayern said Neuer had "a reaction in the calf muscle" and would need to sit out training "in the coming days".
