Tottenham forward Clinton N'Jie is set for a lengthy spell on the sidelines after undergoing surgery on his injured knee this week.
The off-season signing from Lyon suffered medial ligament damage following a clumsy challenge from Monaco midfielder Jeremy Toulalan in their Europa League clash last week.
Spurs boss Mauricio Pochettino conceded after his side's 4-1 win that N'Jie was likely to be ruled out of action for a lengthy spell, and the club have now confirmed the Cameroon international has gone under the knife to repair the problem.
The Les Gones youth product has yet to start for the north Londoners in the Premier League this term, but made seven appearances off the bench and provided the assist for Harry Kane's goal in the 4-1 win over Manchester City on October 26.
A statement from Spurs read: "Clinton N'Jie has undergone surgery to the medial collateral ligament of his right knee.
"Our medical staff will monitor Clinton's progress during his rehabilitation to determine when he will be ready to return to training."
