Arsenal have confirmed that club captain Cesc Fabregas is set to be out of action for two weeks with a hamstring injury.
The Gunners have also announced that Emmanuel Eboue will be missing for at least four weeks as he nurses a knee ligament problem.
Both men sustained the injuries during Tuesday’s 2-0 defeat to Braga in the Champions League.
“Eboue has a medial knee ligament strain,” manager Arsene Wenger told Arsenal TV Online.
“It can be four weeks, can be six weeks or can be eight weeks. But I think it will be four weeks minimum.
“Fabregas will be assessed today (Thursday) with a scan. After that we can tell you how long he will be out, but I count two weeks.
“It is a big blow because it will question how cautious we have to be in the future with him. Cesc has played 50 games a year since a young age. We may have to be more cautious with him, especially in the next two months.”
