Bad news for Real Madrid, as Sergio Ramos was forced to leave the match against Sevilla with a muscle problem. The Spanish defender will likely miss Saturday's Derby against Atlético de Madrid because of this injury. With Ramos and Pepe out, Ancelotti will need to start Varane and Nacho in the center of the defensive line, and both are reserves when Pepe and Ramos are healthy.
Further updates on this apparent hamstring injury should come up as soon as he gets tested this Thursday, but again, his presence on Saturday's Derby seems quite unlikely. It is a very cold night in Madrid, so the injury is probably related to a lack of proper warm-up exercises. Ramos was able to leave the field on his own, so he should not miss a lot of time, and Pepe might be ready for the Champions League tie against Schalke too.
Ancelotti will need to figure something out for his defensive line.
