Crocked Khedira handed World Cup boost
The 22-year-old Stuttgart player, who won his second international cap against Argentina earlier this month, suffered the injury in the 2-1 victory over Bayern Munich on Saturday and will be sidelined for around three to four weeks.
"Sami was lucky. He looks to have escaped without surgery and in the best case scenario he could be back after three or four weeks," Stuttgart team doctor Raymond Best said on Sunday.
Khedira, whose form has been key in Stuttgart's rise up the table to seventh after a poor start to the season, is chasing a place in Germany's squad for the World Cup in South Africa in June.
Coach Joachim Low is expected to announce his preliminary squad in early May.
