Karim Benzema underwent tests after training on Friday and although he was given the all-clear, Real Madrid are taking no risks.
Real Madrid will once again be without Karim Benzema when they face Girona on Sunday and Rodrygo is also an injury doubt.
Captain Benzema trained on Friday, but the Ballon d’Or winner is still troubled by muscle fatigue in his left leg.
Los Blancos head coach Ancelotti revealed on Saturday that his star forward had passed tests that were clear.
However, Madrid will not risk the French international’s fitness, while forward Rodrygo may also miss the LaLiga clash with Girona at the Santiago Bernabeu.
Ancelotti said of Benzema: “He trained yesterday, then he didn’t feel very well. We had some tests and everything was fine, but we want to be careful.
“The tests were pretty positive, there was no problem, but he doesn’t feel 100 percent, so we’ll take it easy with him.
Rodrygo did not train on Saturday due to an unspecified injury and his fitness will be assessed on match day.
Luka Modric, Federico Valverde and Dani Ceballos are set to return to the top of the league.
Madrid beat RB Leipzig 3-2 in the UEFA Champions League on Tuesday and Ancelotti is expecting a response from his players.
The Italian said: “I think the team learned [from the loss to Leipzig] that we have to prepare for every game as if it were the most important of the season.
“Sometimes when you play every three days you need to recover physically and it’s not easy to always stay motivated.”
