Havertz, who earns £275,000-a-week at the Emirates Stadium, had recently returned to action after a knee injury sustained in the opening game of the season against Manchester United. However, his latest injury is unrelated to the previous knee issue and is expected to keep him out for several games, including the FA Cup clash against Wigan Athletic and Premier League matches against Brentford and Wolverhampton Wanderers.
Manager Mikel Arteta had expressed optimism about Havertz's progress, stating that the forward was "very close" to making a full return. However, the injury is a significant blow to Arsenal's title hopes, with Manchester City closing in on the top spot.
