Arsenal have confirmed Thomas Partey faces a stint on the sidelines.
The Ghanian midfielder limped off during Monday's terrible 3-0 loss to Crystal Palace.
The club have now confirmed that Partey has suffered a thigh injury after completing scans.
"Thomas has since received further assessments, and a subsequent scan has shown muscle damage to his right thigh," an update from the club read.
"We will continue to assess Thomas in the coming weeks, during which time he will also receive further specialist consultations."
