Spurs manager Thomas Frank says he will hold talks with defender Djed Spence after an incident during their 3-0 defeat to Nottingham Forest.
Callum Hudson-Odoi's brace and a superb 25-yard strike from Ibrahim Sangare sealed a comfortable victory for Forest at the City Ground.
Spurs, meanwhile, had just one shot on target, with defender Archie Gray being dispossessed just outside his own penalty area for Forest's first goal after receiving a short pass from goalkeeper Guglielmo Vicario.
Frank's side now sit in 11th place in the Premier League and with just one win in their last seven matches.

Spurs fans have been calling for the Dane to be sacked due to the manner of their recent performances.
Frank was also criticised for his substitutions in the Forest defeat, with centre-back Ben Davies and defensive midfielder Joao Palhinha being brought on when Spurs were 2-0 down.
Making way for Davies close to the hour mark was Spence, who was transformed into one of England's best full-backs under Ange Postecoglou last season.
Spence appeared to be less than happy after being subbed off, with the London Evening Standard reporting that he gestured towards the bench upon seeing his number go up, before then throwing a jacket to the floor as he walked back to the dugout.
Frank told reporters post-match that, although he didn't see the incident, he would promptly discuss the matter with the England international.
"You're the third one that said that to me today," he said when asked about the incident.
"I didn't see it. Of course I will look back to be aware of it.
"I think there can be three reasons. He can be disappointed with his own performance, the team's performance, he can be disappointed with being subbed off. I'll ask him about that."
Spurs are next in action on Saturday when they host Liverpool at the Tottenham Hotspur Stadium.
