Real Madrid have suffered a major injury blow following their 2-1 defeat in the LaLiga derby on Sunday.
The Los Blancos confirmed in a statement via their website after the game that captain Fede Valverde sustained an ankle injury.
Valverde suffered a strong tackle from Atlético’s Kang-In Lee, which went unpunished by the referee.
The Uruguay midfielder was diagnosed with a severe trauma to his left ankle after Atletico defeated Jose Mourinho’s side.
Valverde will now undergo further tests in the coming hours.
The 28-year-old will hope to recover on time to play for Real Madrid when they face Villarreal in their next game after the international break.
