Tottenham duo Cristian Romero and Pierre-Emile Hojbjerg are doubts for Wednesday’s Champions League clash with Sporting.
Both players missed Sunday’s 2-1 Premier League defeat against Newcastle due to injury.
Romero has a calf problem, while Pierre is struggling with a thigh issue.
Spurs are already missing Richarlison and Dejan Kulusevski, who Conte confirmed will not be fit to return against Sporting.
Asked if Romero or Hojbjerg will be fit to face for Wednesday, when Spurs can secure qualification to the Champions League knockout stage, Antonio Conte said: “If you ask me in this moment, I don’t have an answer because I don’t know the way they recover from this fatigue and this situation.
“Romero was the last two or three games, he arrived every day half and half to decide if he play or doesn’t play. I think in the past we have taken risk.
“The players gave their availability to play otherwise honestly if the player doesn’t want to play, I don’t force the player. Now after the game against United, he felt a lot of fatigue and then yesterday he felt fatigue in his calf. Before in his thigh, the right. Now left in the calf.
“Pierre it was the same because Pierre played every game, he played every minute and he was really tired.”
