Jan Vertonghen is facing a spell on the sidelines after limping out of Tottenham’s 3-1 win at Crystal Palace with a knee injury.

The Belgium international will undergo tests at Spurs’ Enfield training headquarters on Sunday amid fears he could be out for weeks.

Vertonghen clashed with Palace striker Connor Wickham and clutched his head and knee before he was substituted at Selhurst Park at the 74-minute mark as his partnership with Toby Alderweireld was halted for the first time in the Premier League this season.

Up until that point, the Belgium international duo had played every minute of Spurs’ Premier League campaign.

Vertonghen took to Twitter after the match to reveal there was “no update on the injury yet”, a point echoed by manager Mauricio Pochettino.

Speaking at his post-match media conference, Pochettino said: “Jan, we will assess tomorrow. It looks painful but we will assess it tomorrow and see how he is. I don’t want to make any judgement now.

“We will wait to look at the incident too. He is feeling not so good, his knee also. He didn’t speak to me about the incident yet.”
