Arsenal were sweating over another potential injury blow on Thursday night after one of their stars suffered an awkward fall on international duty.
Riccardo Calafiori looked to injure his left knee after slipping unprompted in the 92nd minute of Italy's 2-1 Nations League quarter-final defeat by Germany.
The defender immediately held his knee and had to come off for what remained of the game, leaving Italy with 10 men.
Now the Gunners will anxiously await the results of testing and hope he doesn't join Bukayo Saka, Kai Havertz, Gabriel Jesus, Takehiro Tomiyasu, and Raheem Sterling on the treatment table.
