Arsenal boss Arsene Wenger has confirmed that Laurent Koscielny is due to have a scan on Friday to determine the extent of his injury.
The French international picked up the problem in the 5-1 defeat to Bayern Munich in midweek, and after hobbling off in the second half, it looked like a hamstring strain.
With Arsenal facing Sutton in the FA Cup this weekend, Wenger is likely to ring the changes in his starting line-up anyway, but he will not want to be without his influential captain for long.
As seen in the second half against Bayern without Koscielny, the Gunners fell apart and conceded at will as they saw their Champions League dreams for this year shattered by the Bavarian giants.
However, there was no immediate positive news from the Arsenal boss as he confirmed that a scan on Friday would reveal more.
Wenger says Koscielny will have a scan today. Will play a "normal" team against Sutton on Monday.

The 67-year-old wouldn’t go into more detail regarding his selections for the game in general, and at this point given recent results, he would arguably be wise to start a strong team rather than rotate too much and give his youngsters another opportunity.
As they look set to fall short yet again in their pursuit of a major trophy, the pressure is really on Wenger and after spending the majority of his press conference on Friday responding to questions about his future, he was keen to insist that the priority for now remains what happens on the pitch until the end of the season.
An FA Cup exit at Sutton would be absolutely disastrous, and so with or without Koscielny, the Gunners are going to have to find a way to win and win well.
