Arsenal have confirmed a double injury blow ahead of the Premier League clash against Leeds United on Sunday.
The north London giants have recently lost momentum with a three-match winless run which has included two defeats.
They are scheduled to host the Whites at the Emirates this weekend, but ahead of the game, two players have been ruled out with injuries.
Kieran Tierney has been nursing a lower leg injury over the past 21 days and he is only expected to return to training next week.
The Ghanaian is set to spend another spell on the sidelines and the club have not revealed a suitable return date for the midfielder.
The Gunners are currently 11th on the table and a victory would see them leapfrog Leeds, who are in front of them at the moment.
Following the clash, they will make the trip to Rome for the first leg of the Europa League round of 32 against Benfica.
