Arsenal will be without the likes of Mohamed Elneny and Rob Holding this weekend.
The Gunners are preparing for a tough game against Burnley away from home on Saturday.
The club's medical team confirmed that Holding is struggling with bruising on his right knee, as a result of a training collision.
Meanwhile, Elneny is absent due to a hamstring problem that he sustained in a friendly game against Brentford recently.
Arsenal will be hoping one or both players are back when they take on AFC Wimbledon in the Carabao Cup, and then Tottenham in the Premier League.
