Arsenal will take on PSV Eindhoven in a rescheduled Europa League fixture on October 20 - meaning the Gunners' clash with champions Manchester City will be postponed.
UEFA confirmed earlier this week that this Thursday's planned fixture between Arsenal and PSV was called off due to logistical issues relating to the Queen's funeral.
The governing body said that there were "severe limitations on police resources and organisational issues related to the ongoing events surrounding the national mourning for Her Majesty Queen Elizabeth II".
The September 15 fixture will now be played on October 20 - a day after the Gunners were due to take on Pep Guardiola's Man City.

As a result, the clash with the Citizens at the Emirates has now been called off and will need to be played at a later date.
A date for Man City's visit to Arsenal is yet to be confirmed.
A UEFA statement on Wednesday read: "UEFA today announced that the UEFA Europa League tie between Arsenal FC and PSV Eindhoven, originally scheduled to be played on Thursday 15 September, will now be played on Thursday 20 October at 19:00 CEST (18:00 local time).
"The rescheduling of this match was possible after the decision of the Premier League to postpone the domestic match between Arsenal FC and Manchester City FC originally due to be played on 19 October.
"UEFA would like to thank the Premier League and the clubs concerned for their flexibility and cooperation in the rescheduling of the UEFA Europa League match which had been postponed due to the impossibility for local police forces to guarantee its secure staging."
