Arsenal will have to turn once more to an emergency stand-in at right-back for Saturdays Premier League trip to Brighton & Hove Albion.
The Gunners are missing both Ben White and Takehiro Tomiyasu through injury and have now lost Jurrien Timber due to suspension the yellow card shown to the Dutchman during Wednesday night's win over Brentford was his fifth of the season and equates to a one-match ban.
It points to Thomas Partey returning to right-back on the south coast at the weekend, which has knock-on effects for other parts of the team by removing the Ghanaian from midfield.
Partey has already played at right-back this season a number of times in the Premier League, Champions League and Carabao Cup. Versatile defender Riccardo Calafiori is another emergency option but the Italian started his first game since November at Brentford - and it showed.
Arteta is already dealing with a seasonal illness ripping through his squad, which was the reason for Kai Havertz's absence in midweek. The German appears to have been the worst affected, but the boss has revealed that others who were playing against Brentford were also suffering.
"It affected players on the pitch and off the pitch," Arteta said of the bug.
"It is nothing serious. But it wasn't the ideal situation. In relation to the symptoms, with Kai it was obvious. He wasn't feeling well at all. He had very clear symptoms to stay away from, put him in a car, and go back to [home].
"These things happen. In this period, there are always things thrown at you, infections, viruses, so I try to delay the lineup as late as possible because you can get up in the morning and unfortunately have a surprise like this."
Arsenal are next in action away to Brentford on Saturday evening before the first leg of a Carabao Cup semi-final against Newcastle United next Tuesday.
