Arsenal defender Mathieu Debuchy has suffered a setback in his recovery from injury and is set to miss the Gunners visit to the KC Stadium to face Hull City on Monday night.
According to the London Evening Standard, the Frenchman has picked up a slight hamstring strain in training and is a 'major doubt' for the Hull match.
The former-Newcastle defender has been bitten by the injury bug this season, a combination of ankle and shoulder problems restricting his first-team starts to just 10 so far this season.
Both the ankle and shoulder injuries required surgery, although this latest complaint is thought to be much less severe.
The France international, 29, featured against Reading in Arsenal's victorious FA Cup semi-final, but he may now drop back out of the team for Premier League duty in the north east.
Hector Bellerin has emerged in Debuchy's absence this season, and the Gunners seem to have a real top prospect on their hands in the form of the ex-Barcelona academy star.
But to lose a senior player of Debuchy's quality is always a blow for Wenger.
Speaking to reporters ahead of the game, Wenger said: "Everybody is in good shape, apart from Mathieu Debuchy, who has a little hamstring problem.
"We don't know how bad it is. Apart from that everybody should be available [for the Hull match]. Monday could be too early for him. He got the injury in training.
“We are at a period of the season where it’s going to be important to have everybody on board and to see everyone fit makes us stronger. We are on a good run, we want to keep it going and the fact that we have plenty of [selection] opportunities is very interesting for me.”
What do you think Arsenal fans - just how big a blow is it to lose Debuchy again, and how confident are you in Bellerin to deputise?
