Thomas Partey suffered another setback in Arsenal’s League defeat to Aston Villa on Saturday.
The midfielder could not last the entire minutes of the game as he came off in the 74th minute over a suspected knock.
Partey was replaced by Willian with the Ghanaian now expected to undergo checks.
The Ghanaian has already missed 10 games due to injury since joining the Gunners.
Meanwhile Arsenal boss Mikel Arteta who is under intense pressure will look forward to have his trusted midfielder back for the team’s next game against Leeds United.
