Arsenal defender Kieran Tierney was forced off in the first half of Scotland's 2-1 win over the Republic of Ireland. Tierney took a blow to the head in the 42nd minute and had to be replaced.
Some Gunners players who have gone away on international duty this month have experienced injury problems. Thomas Partey - who only returned to the Arsenal team last week for the 3-0 win at Brentford - has been sent back to London as a precautionary measure after picking up a knee injury before Ghana's defeat to Brazil on Friday.
Meanwhile, Oleksandr Zinchenko was forced to miss Ukraine's fixtures through injury, while Martin Odegaard has been carrying a knock, although he did start for Norway in their game against Slovenia on Saturday.
