Martin Odegaard missed Norway training on Tuesday due to an ankle injury, with the national team’s medical staff in “continuous contact” with Arsenal.
The Arsenal captain suffered the issue on Sunday night against Portugal, when he was kicked from behind by Bernardo Silva in the final minutes of the match.
Odegaard furiously confronted Silva and he was just as firm after the match, stating that the challenge "doesn't belong on a football field".
He was seen limping out of the stadium and Odegaard admitted he was unsure if he would be fit to face Wales on Thursday night.
Norway are continuing to assess Odegaard and manager Stale Solbakken confirmed that regular updates are being sent back to Arsenal.
“The medical sector reports what has happened, and now it is the case that every metre you run here, and all training and everything you have done, is sent to the club," Solbakken said.
"The medical contact is almost continuous. It’s standard procedure. I don’t interfere with that. There are four or five people for that, so they have to manage that.”
Norway have two more matches during this international break.
They travel to face Wales on Thursday night, before taking on Portugal in Porto on Sunday. What role Odegaard is able to play in those fixtures remains to be seen.
Norway trained on Tuesday morning but Odegaard did not take part in that session. His ankle is said to still be too painful for him to return to training, leaving him as a doubt for the Wales clash.
Assistant coach Brede Hangeland said: "Martin was in the breakfast room, he was happy and he had less pain in his ankle than yesterday.
"It's a long time until the next game, it's a full two and a half days. A lot can happen in that time. Martin will be allowed to do what he wants in training today with regard to his ankle, and I'm glad it's much better than yesterday."
It has already been a frustrating international break for Arsenal.
Kai Havertz had to return to the club early with a hamstring injury picked up in Germany's first match, while Ezri Konsa missed England training on Monday with a "minor issue".
