Tottenham boss Antonio Conte is worried about the extent of Cristian Romero's hamstring injury.
The Argentina defender sustained the muscle issue in his country's 0-0 draw with Brazil in a World Cup qualifier last week.
The problem ruled the 23-year-old out of Spurs' victory over Leeds last weekend and manager Conte has admitted the injury is "serious".
"We are waiting for another scan," he said ahead of Spurs' Europa Conference League trip to Mura.
"I think his injury is a bit serious. We have to wait. I don't know how long he will need to recover. His injury is worse than (Giovani) Lo Celso and (Dane) Scarlett.
"He needs another scan, then the doctor can give more details."
