A hamstring injury has limited Yaya Sanogo and will keep him out of Arsenal's next match.
The club's official Twitter account provided the latest info Monday:
Manager Arsene Wenger spoke about the injury, via James Olley of the London Evening Standard:
Sanogo started at striker for Arsenal in the squad's opening English Premier League match against Crystal Palace. While he did not get onto the scoresheet, his side were able to escape with a narrow 2-1 win to begin their league year with three points.
However, he will clearly not be able to help out the club as they travel to Besiktas for the first of a two-legged play-off to earn a spot in the UEFA Champions League group stage.
Olivier Giroud, who replaced Sanogo in the 62nd minute of last match, will likely be the first option to replace him in the starting XI.
Still, Arsenal are expecting a lot out of the 21-year-old striker this season and will hope for a return as soon as possible.
