Borussia Dortmund striker Erling Braut Haaland has ruled himself out of the weekend's clash with Augsburg on Saturday.
Haaland is also a doubt for Norway's upcoming World Cup Qualifiers, with a leg knock.
"I can't play tomorrow. I am injured. I'll be back soon," the 21-year-old wrote on Twitter Friday.
Norway play crucial qualifiers against Turkey next Friday and Montenegro on October 11 in their bid to reach the 2022 World Cup in Qatar.
Haaland missed Dortmund's 1-0 Bundesliga defeat at Borussia Moenchengladbach last Saturday and Tuesday's Champions League home win against Sporting Lisbon by the same scoreline.
"Erling will be out once again. The pain is too strong, it's not possible," Dortmund coach Marco Rose said.
"He tried, but had to stop running in training."
Dortmund are fourth in Germany's top flight, four points behind leaders Bayern Munich after six games.
The striker, who has scored a staggering 68 goals in 67 appearances for Dortmund since he joined in January 2020, has missed the last two games with a leg knock.
