Arsene Wenger is facing another midfield injury headache after Francis Coquelin suffered a broken nose on Sunday . The Frenchman will discover today whether he needs surgery after he was injured in a nasty collision with team-mate Olivier Giroud before taking another blow in the closing stages . Should he need an operation , Coquelin could expect a prolonged period on the sidelines , but even if a procedure is n't required the midfielder is a doubt for Wednesday 's trip to Queens Park Rangers . Arsenal midfielder Francis Coquelin broke his nose after two knocks to the face on Sunday against Everton . After a lengthy stoppage out , Coquelin was allowed to return the field of play having received treatment . This clash of heads in the second-half left Coquelin with bloody gushing out of his nose . Arsenal are already without key central midfielders Mikel Arteta and Jack Wilshere , while Aaron Ramsey and Mathieu Flamini , who did n't feature on the bench yesterday , only returned to training at the end of last week . 'Yes , Coquelin has broken his nose . If he needs surgery or not I do n't know , ' said Wenger . Coquelin needed lengthy treatment following the clash of heads in the 67th minute but played on until the 89th when he was hauled off after taking a second blow as he went up for a header with Steven Naismith . Coquelin is evidently in pain on the ground after a collision with Giroud broke his nose at the Emirates . And Wenger revealed it was the 23-year-old 's decision to continue playing . 'After he took a hit on it again I had to take him off , ' Wenger added . ' I had been told by medical people he could stay on and he wanted to stay on . ' Arsenal keeper David Ospina made three excellent saves to shut out Everton and manager Roberto Martinez said : ' I felt we were the ones creating the chances and when you create them you need to take them .
