Arsenal have recalled Francis Coquelin from his loan with Charlton Athletic.
Arsene Wenger has a defensive crisis on his hands with Per Mertesacker the only fit centre-back.
Laurent Koscielny and Nacho Monreal are injured while Calum Chambers is suspended.
Coquelin, 23, is a defensive midfielder but he can also play at the back.
An Arsenal statement read: "Francis Coquelin has returned to Arsenal from his loan spell with Charlton Athletic.
"The 23-year-old featured five times for the Championship club during his six weeks at the Valley.
"Coquelin will be available for selection for Saturday's Premier League match against Newcastle United."
