Everton have been boosted by the news that Dominc Calvert-Lewin's hamstring injury is not as serious as first feared.
The England striker will miss Sunday's match against Fulham after being taken off with the problem in the midweek 5-4 FA Cup victory over Spurs, but will be back for the visit of Manchester City next Wednesday.
Ancelotti had initially thought "something wasn't good," but he is relieved that his top-scorer will miss only one match due to the strain.
He said: "Dominic only had a sensation in his hamstring, a feeling that something wasn't good. However, it is only a little problem and he will be able to play on Wednesday (against Man City)."
