Arsenal manager Mikel Arteta admits he is concerned about Thomas Partey after he suffered an injury in the 3-0 loss to Crystal Palace on Monday.
In the build-up to Palace's third-goal, Partey seemed to suffer a muscular injury and subsequently limped off.
Asked about Partey, Arteta said: "I don't know but he felt something in the same area that he got injured previously so that's a big concern."
Partey spent the past week helping Ghana qualify for the World Cup 2022.
The 28-year-old had previously suffered a groin injury late last year.
