Arsenal captain Martin Odegaard will miss 'at least' three weeks of football, according to Norway's doctor.
Odegaard injured his ankle in a Nations League meeting with Austria on Monday, and limped off the pitch before returning to London to undergo an MRI scan.
The pivotal midfielder will miss Arsenal's upcoming North London Derby, with the Gunners also without Declan Rice and Mikel Merino.
Arsenal also take on title rivals Manchester City later this month and begin their Champions League campaign away to Atalanta on Thursday, September 19.
