Arsenal defender David Luiz will miss Saturday's Premier League game at home to Liverpool because of a knee problem, the north London club said.
The Brazilian, who has played 19 league games this season, felt discomfort in his right knee, Arsenal said in a statement on Friday.
Winger Bukayo Saka (hamstring), playmaker Emile Smith Rowe (thigh) and midfielder Granit Xhaka (illness) will undergo a late fitness test.
Winger Willian is available for selection after recovering from a calf injury.
Arsenal are ninth on the table with 42 points after 29 games, four points behind Liverpool, who are seventh.
