Real Madrid captain Sergio Ramos is doubtful for Saturday's El Clasico clash with Barcelona after picking up an injury in a collision with team-mate Casemiro.
The centre-back aggravated a hamstring injury after tangling with the Brazilian during Wednesday's Copa del Rey semi-final second leg defeat to Barcelona, per Jose Felix Diaz at Marca.
Ramos "will be examined by the medical staff on the day of the game" but could be forced to sit out the La Liga clash at the Santiago Bernabeu, per the report.
