Arteta did not name Havertz among the potential absentees ahead of the trip to Brentford, though was only specifically asked about Bukayo Saka, Martin Odegaard, Leandro Trossard and Max Dowman.
He said: "Max is still not available. The rest we will see with the medical team."
The Arsenal boss was also asked about Mikel Merino, who recently underwent surgery on his foot. He added: "The doctors were really happy with the way it went. The time frame we're talking about is months, whether it's three, four or five, I don't know."
