Arsenal manager Arsene Wenger has revealed Mathieu Debuchy is expected to miss the next Premier League game against Hull City on Monday 4 May after the right-back suffered a new injury setback while training.
The France international has been plagued by injuries during his debut campaign at the Emirates Stadium following his summer arrival from Newcastle.
The 29-year-old missed much of the first part of the campaign and underwent ankle surgery in September 2014 after suffering an injury in the fourth Premier League game of the season against Manchester City.
Having resumed his position in December, Debuchy missed another three months of competition after needing another operation on his shoulder following a collision with Stoke City's Marko Arnautovic during the 3-0 win over Stoke City on 11 January.
Debuchy made a surprising return to action when he started during the FA Cup semi-final win over Reading on 18 April but, having being an unused substitute during the draw against Chelsea, Wenger has now revealed he is once again unavailable for the trip to Hull.
"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 game]," the manager said.
"Monday could be too early for him. He got the injury in training."
Meanwhile, Wenger has hailed the importance of regaining momentum for the last part of the campaign, with the Gunners trying to secure second place in the league and hold on to the FA Cup title in the final against Aston Villa.
"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."
