Arsenal fear Oleks Zinchenko’s calf injury is more serious than first believed.
Zinchenko is now expected to miss some key fixtures including Arsenal’s clash with Brentford.
The Football Federation of Ukraine have confirmed that Zinchenko will miss the upcoming international break due to injury.
An official statement read: “Oleksandr Zinchenko will not be able to help the blue and yellow during the September matches in the UEFA Nations League.
“The Arsenal player suffered a calf muscle injury during training at the club which will require two weeks for treatment and recovery.
“Oleksandr immediately personally informed the head coach of the Ukrainian national team, Oleksandr Petrakov, of the unfortunate news by calling him. We wish Sashka a speedy recovery.”
Ukraine are set to face Scotland in a double header this month as well as Armenia, but Zinchenko will play no part in the games.
Instead, he will remain in London to undergo treatment in a bid to return to action before the North London Derby, which is due to take place on October 1.
