Arsenal boss Mikel Arteta is not optimistic about Thomas Partey's injury.
The Ghana midfielder limped off in the first half of Sunday's 2-1 friendly loss to Chelsea
Partey appeared to suffer an ankle injury following a tackle by Chelsea forward Hakim Ziyech.
Asked about the former Atletico Madrid man, Arteta said: "At the moment, it's not looking good because he was in pain and he could not continue.
"He'll have a scan tomorrow. At the moment it's not looking good."
