Real Madrid are reportedly facing a crisis ahead of their upcoming games against Levante and Paris Saint-Germain, with Toni Kroos the club's only fully-fit midfielder.
Los Blancos will be looking to return to winning ways in La Liga on Saturday afternoon before visiting PSG in their first Champions League group match next week.
Isco and James Rodriguez are still on the sidelines for Madrid despite stepping up their recovery from injuries, while Luka Modric and Federico Valverde have also recently picked up issues.
According to Marca, Casemiro has only participated in one training session ahead of the Levante match, meaning that Kroos is currently the club's only fully-fit central midfielder.
The summer exits of Dani Ceballos and Marcos Llorente has left Zinedine Zidane with a small pool of midfielders to choose from.
Manchester United's Paul Pogba was strongly linked with a move to the Bernabeu during the summer transfer window, but the Spanish giants could not convince the Red Devils to sell the 2018 World Cup winner.
