Thomas Partey picked up an injury during Arsenal’s 1-0 defeat to Manchester City in the FA Cup on Friday night.
The Ghanaian midfielder felt some discomfort and was withdrawn at half-time.
He is expected to undergo an MRI scan today to determine the full extent of the injury.
Nathan Ake grabbed the only goal of the game on 64 minutes to seal City’s place in the fifth round.
“He had some discomfort and it was getting worse and worse,” Arteta said after the game.
“He was uncomfortable to continue. (Saturday) or the day after he will have an MRI scan and see what he has,”
“We have at the moment the injury of Mo (Elneny). It is not possible to get him fit. Sambi has come in and has done well. It is true Thomas is a big influence and a big personality and in the second half we didn’t have him,”
