Kai Havertz has undergone surgery on the knee injury that kept him out of Arsenal’s win over Leeds United last weekend.
The Germany international suffered a serious hamstring injury last season but recovered in time to feature in the final two games of the campaign.
Havertz faces increased competition for his place this term following the signing of Viktor Gyokeres and started on the bench in a 1-0 victory against Manchester United on the opening weekend.
The former Chelsea star suffered a setback during that game after replacing his new teammate on the hour mark.
Arsenal were hoping Havertz would avoid having to go under the knife but having decided on a course of action they remain hopeful his absence will be a short term one.
