Emerson Royal will miss a string of important games for Tottenham in the Premier League run-in after he undergoes surgery on a left knee injury.
The Brazil international faces a battle to play again this season, with the news of his setback coming as the club head into their final 10 games of the league campaign.
Spurs have Pedro Porro at their disposal at right-back, and the Spaniard is set to have a run in the side with Emerson Royal sidelined.
The north London giants let Matt Doherty join Atletico Madrid on loan in January, so acting head coach Cristian Stellini will hope Porro stays fit.
Tottenham said in a statement: "We can confirm that Emerson Royal suffered a meniscus injury to his left knee while on international duty with Brazil last week.
"The defender will undergo surgery before beginning his rehabilitation with our medical staff."
Emerson Royal has made 32 appearances for Tottenham this season, taking all competitions into account, including 23 starts.
He played in Brazil's 2-1 friendly defeat to Morocco on Saturday, suffering the injury in the 90th minute after a challenge from Sofyan Amrabat.
