He will miss Sunday's trip to West Bromwich Albion in the league and against Norwich City on Oct. 19, as well as France's final World Cup qualifier against Finland on Oct. 15 and an international friendly against Australia four days earlier.
The injury will also keep him out of Arsenal's Champions League match against Borussia Dortmund on Oct. 22.
"Sagna will be not be available, he has a hamstring injury and will be out for three weeks," Wenger told a news conference.
Carl Jenkinson is most likely to take his place this weekend.
