Arsenal captain Martin Odegaard is set to be out for at least three weeks with an ankle injury, according to Norway's team doctor.
Ola Sand said there is "probably no fracture" to Odegaard's left ankle, which he injured while playing for Norway on Monday, but added that an absence of less than three weeks would be "just a bonus".
Odegaard limped off during Norway's Nations League win over Austria and on Tuesday the 25-year-old midfielder returned to London, where he underwent an MRI scan.
Arsenal have said that manager Mikel Arteta will provide an update during his news conference on Friday, before Sunday's north London derby at Tottenham.
