Arsenal captain Laurent Koscielny has returned to full training ahead of their Super Sunday clash against Manchester City.
It was feared Koscielny had suffered a fractured jaw after he was forced off in Arsenal's 3-1 defeat to Manchester United in the FA Cup fourth round last Friday.
However, scans later revealed he had only suffered bruising and soft tissue swelling on his face and jaw.
Meanwhile, Ainsley Maitland-Niles (right knee) and Henrikh Mkhitaryan (right foot) are being assessed before Sunday's trip to City in the Premier League, live on Sky Sports.
Hector Bellerin, who has been ruled out for six to nine months, underwent successful surgery in Spain on Wednesday to repair an anterior cruciate ligament injury to his left knee.
Sokratis Papastathopoulos, who also came off early in last week's defeat to United with injury, is expected to return to full training by the end of February as he recovers from a problem with his left ankle.
Danny Welbeck (right ankle) and Rob Holding (left knee) are both recovering after undergoing surgery.
