Cesc Fábregas could be out of action for up to three weeks after injuring his hamstring in Arsenal's Champions League defeat by Braga,
according to manager Arsène Wenger.
Fabregas was substituted in the 69th minute of the 2-0 loss in Portugal,
while Emmanuel Eboué was also hurt,
suffering a knee injury.
"Eboué will be out for a while and we will have to asses Fábregas,
" Wenger told the club's website.
"It could be two to three weeks. It is very disappointing because I had a hesitation to play him before the match started.
I took the gamble and it backfired on us."
Arsenal face Aston Villa in the Premier League on Saturday and Wigan in the League Cup quarter-finals on Tuesday.
