Leicester winger Marc Albrighton is likely to miss the rest of the season with a hamstring injury.
Albrighton pulled up in training ahead of last weekend's 1-0 defeat by Manchester United at the King Power Stadium.
Manager Claude Puel revealed the winger needs surgery and is doubtful to be back before the end of the season.
"It's bad news for us, for the team," Puel said.
"It's serious yes, a serious injury. I think he will not be available perhaps until the end of the season. We will have to see about this.
"Mark gave us spirit, hard work on the pitch for the team and of course now we will have to find other balance for the team.
"It will be a bad thing for him, for us, but it will be a chance for other players to show their quality."
Daniel Amartey also remains out ahead of Sunday's trip to Tottenham - live on Sky Sports - but new signing Youri Tielemans is in contention for his first start since joining on loan from Monaco on deadline day.
Puel also denied he has a problem with Jamie Vardy after the striker appeared to react angrily after the defeat to Manchester United.
"I have a good relationship with him. We know Jamie and after he has lost, he is never happy and that is normal for a player," Puel said.
