Arsenal midfielder Alex Hleb has been ruled out for three weeks with a hamstring injury.
The 26-year-old Belarus international picked up the injury during the 2-1 Euro 2008 qualifying victory over Holland on Wednesday.
Hleb, who has been in fine form, will miss the visit of Wigan on Saturday and is likely to be ruled out of Arsenal's two remaining Champions League games.
"He will be out for 21 days," boss Arsene Wenger told the club's website. "So once again we lose someone during this period."
