Arsenal defender, William Saliba is expected to be unavailable for their trip to Manchester City on Wednesday night for their crucial Premier League clash, The Athletic reports.
Saliba has been out since their Europa League game with Sporting Lisbon with a back problem.
There are now fears the French defender could miss the rest of the season.
Arsenal have been assessing his condition, but it appears the trip to the Etihad Stadium will come too soon.
Saliba has missed their last five games, with Rob Holding starting in the 22-year-old’s absence.
Mikel Arteta’s men have failed to keep a clean sheet during that period.
Arsenal have conceded nine goals, seven of which have come in the last three matches.
