Everton suffered a shock 2-0 defeat at Goodison Park against Fulham as they missed the opportunity to close the gap on the rivals competing for the top four.
Josh Maja scored two second-half goals to seal all three points for the Cottagers.
The Toffees also suffered a blow with the sight of James Rodriguez limping off midway through the second half.
However, in the post-match press conference Ancelotti has revealed that the Colombian has just taken a knock and that his injury is not serious.
Everton will face league leaders Manchester City in the Premier League on Wednesday at Goodison Park, and the Toffees fans will be hoping that Rodriguez can shake off his knock ahead of the game.
