MANCHESTER, England -- Erling Haaland will miss Manchester City's trip to Brighton because of injury, manager Pep Guardiola said on Wednesday.

Haaland was not in the squad for the FA Cup semifinal victory over Chelsea on Saturday after picking up a muscle problem against Real Madrid.

The striker was substituted before extra time as City went out of the competition on penalties and has not trained since.

Guardiola confirmed that Haaland will not play against Brighton at the Amex Stadium on Thursday, although he is hopeful the issue is not serious. Phil Foden and John Stones are set to be available.

"Erling is not ready for tomorrow [against Brighton]," Guardiola told a news conference.

"It's not a big issue but he's not allowed for this game."
