Liverpool midfielder Arthur Melo is set for a period on the sidelines as he needs surgery on an injury sustained during training.
The Brazil international, 26, was a deadline day signing on a season-long loan from Italian giants Juventus.
Speaking on Friday Liverpool boss Jurgen Klopp said Arthur had suffered an injury in training on Monday.
He is now reportedly expected to miss between three to four months as he recovers.
The injury means any lingering hopes he had to play at the World Cup are likely to be over.
Arthur hasn't started a match for Liverpool since he joined.
