Arsenal captain Cesc Fabregas will only be sidelined for a fortnight, according to Gunners boss Arsene Wenger.
The Spain international injured his hamstring during Tuesday's disappointing Champions League defeat to Braga.
However, Emmanuel Eboue, who was stretchered off with a knee ligament problem in the same game, could be sidleined until Christmas.
"Eboue has a medial knee ligament strain," Wenger told the club's official website."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 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.
"We have a lot of bumps and bruises but everyone else should be available this weekend.
"(Manuel) Almunia should be capable to play but I will see how he reacts. (Aaron) Ramsey needs competitive games. He played 45 minutes and he did well. We need to get him slowly and progressively into competition mode."Subscribe to Football FanCast News Headlines by Email
