MANCHESTER, England (AP) — Erling Haaland has suffered a muscle injury and will be assessed ahead of Manchester City’s FA Cup semifinal against Chelsea on Saturday.

City manager Pep Guardiola said the Norway striker felt discomfort during Wednesday’s Champions League quarterfinal against Real Madrid and asked to be substituted. City went on to lose the match on penalties.

Guardiola said Haaland would be monitored ahead of the game against Chelsea at Wembley Stadium.

“We will see. It was a tough game, a lot of action, high intensity for both sides,” Guardiola told a news conference Friday. “Erling felt something, a muscular issue. That’s why he told me he could not continue.

“The (doctor) said he had a little bit of niggles, a little problem, we will see how his evolution is in the next hours.”

The latest potential setback comes after Haaland was out for more than a month from December to January because of a foot injury.
