Noni Madueke is undergoing scans after injuring his right knee during Arsenal’s 1-1 draw with Manchester City on Sunday.
The winger was seen clutching his right knee towards the end of the first half of the game and was replaced at half-time by Bukayo Saka.
An update on the scan is expected on Tuesday during Mikel Arteta’s press conference ahead of Arsenal’s third round Carabao Cup against League One side Port Vale.
The Gunners will be praying for good news on Madueke, who has been one of their shining stars since signing from Chelsea over the summer.
