Arsenal manager Arsene Wenger has revealed that Mathieu Debuchy suffered a dislocated shoulder during his side's 3-0 win over Stoke City this afternoon.
The right-back sustained the injury as he slid off the pitch in the 12th minute, following a challenge with Stoke winger Marko Arnautovic.
Speaking to Sky Sports News after the match, Wenger said: "He has to see a specialist then we see where we go from there. A dislocated shoulder can take a while."
Debuchy, who joined the Gunners from Newcastle United in the summer, had only recently returned to the starting lineup following a spell on the sidelines with ankle ligament damage.
