The England international has been left out of the starting XI for the Gunners' crunch game against Wigan, while Kieran Gibbs returns from injury to take his place at left-back
Kieran Gibbs returns from a hip injury to replace Nacho Monreal at left-back, while Lukas Podolski continues as a lone striker for the Gunners.
Wigan are unchanged from their FA Cup victory over Manchester City on Saturday, with their goalscorer, Ben Watson, having to settle for a place on the bench.
A win for Arsenal would see them leapfrog north London rivals Tottenham into the last remaining Champions League spot. A victory for Wigan would put them one point behind Sunderland in 17th place, with just one remaining Premier League game to be played on Sunday afternoon.
