Unai Emery has revealed Laurent Koscielny should be fit to face West Ham on Saturday.
The Arsenal defender was originally named in Emery's starting line-up for the FA Cup clash at Blackpool on Saturday but pulled out ahead of kick-off with a minor back complaint.
A young Gunners team went on to knock the Tangerines out of the Cup with a comfortable 3-0 victory at Bloomfield Road, with Joe Willock (2) and Alex Iwobi grabbing the goals.
And Emery provided a positive update on the Arsenal defender after the victory.
The Gunners boss said: "It's a small injury and he said he cannot play but we have one week to rest and I think he will be OK."
The biggest drama occurred two and a half hours before the game, when a Blackpool supporter protesting about Owen Oyston's ownership of the club climbed on top of the Arsenal bus and refused to move.
A man was eventually arrested but Arsenal arrived at the ground, via a back entrance, more or less on time having prepared for such an eventuality by bringing a back-up vehicle.
Asked if it had affected their preparations, Emery said: "There was no change for us. We know there are some problems here with the supporters and the team. We have respect for them - the supporters, the club, the team - and we prepared for the match with respect also for this competition."
