After conceding a last-gasp equaliser to Swansea, manager Arsene Wenger revealed the midfield star has suffered a setback in his recovery from the thigh injury which has kept him out since Boxing Day.
Wenger said: "Ramsey is maybe two weeks. He's had a setback.
"He's had some scar tissue, then you have to slow down and the tendon is in a sensitive place. You always have to push but not too far.
"Koscielny is out for a while, after that Ozil is at least two or three weeks."
