Germany have announced that captain Bastian Schweinsteiger has suffered a knee injury while on international duty.
The 31-year-old only recently returned from a two-month absence because of a knee problem for his club Manchester United, but it now seems that he could be back on the sidelines once again.
In a statement, the German Football Association (DFB) said that Arsenal's Mesut Ozil and Bayer Leverkusen's Karim Bellarabi also sat out the national team's most recent training session.
"World champion Schweinsteiger was injured at the end of the session on Tuesday afternoon on his right knee," read the statement. "For further investigation, the captain will now undergo an MRI examination with national team physician Dr Hans-Wilhelm Muller-Wohlfahrt in Munich.
"Ozil and Bellarabi will stay for treatment at the team hotel. World champion Ozil had suffered a blow to his left ankle in the Premier League match on Saturday at Everton. Bellarabi picked up a bruise to his right foot in the Bundesliga match on Sunday against VfB Stuttgart."
Schweinsteiger now looks set to miss Saturday's friendly match against England in Berlin.
