Arsenal's north London derby against Tottenham at the Tottenham Hotspur Stadium on Sunday has been postponed because the Gunners do not have enough available players to field a side.
Premier League rules say a club must play a game if they have 13 outfield players and one goalkeeper available.
It is the 21st top-flight game to be postponed this season because of Covid.
Arsenal said they "reluctantly" requested a postponement because of injuries, positive Covid-19 cases and players away with their countries at the Africa Cup of Nations.
Thomas Partey, Mohamed Elneny, Pierre-Emerick Aubameyang and Nicolas Pepe are on international duty in Africa, while Cedric Soares, Bukayo Saka and Calum Chambers all picked up injuries in Arsenal's Carabao Cup semi-final first leg draw against Liverpool on Thursday,.
