Real Madrid The league The charge of the title was defeated with a draw 1-1 at Vallecano Ray.
The frustration was clear for Ancelotti's players in the final stages Dani Carvajal dismissed for two late bookings.
A sending off will result in an immediate one match ban for the experienced defender and he will now miss the home game against Seville on the 25th of February.
However, the absence of Carvajal will not be the only problem for Ancelotti against the Andalusians, with Eduardo Camavinga taking his fifth league win of the season.
That means the France international will join Carvajal on the sidelines and force another replacement for Ancelotti's injury-hit squad.
Lucas Vazquez will continue to deputize for Carvajal at right back with Toni Kroos potentially stepping in as cover for Camavinga in Real Madrid's midfield.
