Everton will assess the fitness of James Rodriguez after he came off with a calf issue in the draw with Manchester United.
Rodriguez made it 2-2 when he converted Abdoulaye Doucoure's pass as Everton responded with two quick-fire goals at the start of the second-half.
The Colombian was replaced by Gylfi Sigurdsson with just over 20 minutes of normal time remaining and appeared to be discussing an injury issue with Ancelotti as he came off.
And after the 3-3 draw, with a point sealed by Dominic Calvert-Lewin's 95th minute goal, Ancelotti confirmed Rodriguez has a problem with his calf.
"He had a problem on his calf at the end of the first-half," he said.
"We tried for 10-15 minutes [of the second-half] but the calf was tight.
"I prefer to take him off."
Everton play Spurs in the FA Cup on Wednesday and welcome Fulham to Goodison a week on Sunday.
