Arsenal manager, Mikel Arteta, is facing more injury problems within his squad ahead of the visit of Monaco in the Champions League on Wednesday.
Thomas Partey and Jurrien Timber missed training on Tuesday, with Gabriel Magalhaes also still absent.
Arteta has been without Gabriel and Riccardo Calafiori for the last two matches, with Oleksandr Zinchenko joining the injured list last weekend against Fulham.
The trio were absent from training ahead of the visit of the Ligue 1 side, with Partey and Timber also not seen among the group.
With Ben White and Takehiro Tomiyasu also out, Partey has been filling in at right-back in recent weeks.
Timber, who has impressed in a number of defensive roles this season, has been switched over to the left to fill in for Calafiori.
Gabriel and Calafiori both came off in the 5-2 win over West Ham United at the end of November.
