Arsenal manager Arsene Wenger fears defender Mathieu Debuchy could face a lengthy absence after injuring his ankle against Manchester City.
Debuchy was stretchered off in the last 10 minutes of the lunchtime match at the Emirates, shortly before Martin Demichelis' header sealed a 2-2 draw for City and denied Arsenal a come-from-behind victory.
Speaking in his post-match press conference, Wenger said: "Debuchy has a bad ankle sprain. I don't know how long he will be out for, but it does not look too good. They [the medical staff] need more time to assess how long he will be out."
Debuchy has featured in all of Arsenal's matches this season after joining from Newcastle in a 12 million pound deal in the summer.
The player himself later revealed on Facebook that there was no break, and that he hopes to be back "ASAP."

Meanwhile, fears over Danny Welbeck were allayed as he was replaced late on with cramps but should not feel any lingering effects.
