Gabriel Martinelli is expected to be out for almost a month after hurting his hamstring in the Carabao Cup loss to Newcastle, while Gabriel Jesus will miss the remainder of the season owing to a knee injury.
The injury would reportedly see Havertz miss Arsenal's remaining 14 Premier League games, which would be the longest layoff of his career.
It was confirmed on Wednesday that the German attacker tore his hamstring during a warm-weather training camp in Dubai, and although a surgical decision has not yet been made, he could miss the rest of the season.
KAI HAVERTZ's latest injury means Arsenal's list of injured key players extends further.
The former Chelsea and Bayer Leverkusen man has struggled with knee injuries in the past, but the hamstring tear is the first of his career.
