Tottenham face an anxious wait to discover the extent of an injury picked up by Kieran Trippier in the 2-0 pre-season friendly victory over Juventus.
The England right-back appeared to suffer an injury in a challenge with Juventus left-back Alex Sandro during the early stages at Wembley.
After receiving treatment, Trippier continued and delivered a beautifully measured cross moments later for Harry Kane to open the scoring with a 10th-minute header against the Italian champions.
But the 26-year-old was unable to see out the first half and was eventually replaced by Kyle Walker-Peters four minutes before the break.
Trippier was later seen leaving the national stadium on crutches and wearing a protective boot around his right foot.
Manager Mauricio Pochettino said: "Kieran twisted his ankle. We need to assess him on Monday and then we will see.
"Now the feeling is good. It's true that he has crutches, but it's good. We hope that it is not a big issue."
Trippier is Tottenham's only specialised senior right-back following Kyle Walker's departure to rivals Manchester City last month, although Eric Dier has filled in there for Spurs in the past.
Spurs have identified the right-back position as an area that requires strengthening, and Sky sources understand they have considered making a move for Hoffenheim's Jeremy Toljan after cooling their interest in Porto's Ricardo Perreira.
Tottenham are yet to make a signing this summer but also hope to add a new attacking-midfielder to their squad, according to Sky sources, with interest in Everton's Ross Barkley, Leicester's Demarai Gray and Bournemouth's Josh King.
