Arsenal graduate Jack Porter could make a surprise debut against Bolton Wanderers in the Carabao Cup third round on Wednesday night.
The Gunners played out a 2-2 draw against Manchester City in the Premier League on Sunday. David Raya was once again spectacular in goal.
The Spanish star made nine saves with six of them in the box. He was also dominant from corners and set-pieces with three high claims.
Following the game, he was spotted limping and had a bandage on his right leg.
Should he be unavailable for selection, manager Mikel Arteta could be forced to hand a surprise debut to 16-year-old Porter on Wednesday.
Neto is the back-up goalkeeper on loan, but the Brazilian is Cup-tied, having played for Bournemouth in the Carabao Cup this season.
Tommy Setford is the third-choice keeper in the squad after his arrival from Ajax, but he has been absent lately with an apparent injury.
Lucas Nygaard was a summer addition to the academy, but he may not be ready, having just returned to training after a broken thumb.
The 18-year-old has yet to feature for the development squads in the current season.
Arsenal will be hoping that Raya can recover in time for the midweek game at the Emirates Stadium.
Otherwise, there is a genuine possibility that Porter could be handed his first-team bow in a rather unexpected fashion against Bolton.
Porter was recently in the matchday squad for Arsenal’s goalless Champions League draw against Atalanta at the Gewiss Stadium.
