According to report on the Daily Star,
“ARSENAL have suffered a fresh injury blow ahead of Sunday’s north London derby.
Left-back Kieran Gibbs is a doubt for the game with a shoulder injury.
Gibbs played the full 90 minutes on Tuesday as the London giants beat Ludogrets 3-2 in the Champions League.
He was playing in Bulgaria after Arsenal’s regular first-choice left-back Nacho Monreal was ruled out with a thigh problem.
But Gibbs could now replace the Spaniard in the treatment room.
Monreal is expected to return in time for the visit of rivals Spurs at the weekend.
Gibbs could also be fit to feature if he can shake off the shoulder problem”
