Sergio Ramos was forced out of Real Madrid's clash with Sevilla on Wednesday after suffering an apparent leg injury.
The injury occurred less than 10 minutes into the match, with Nacho Fernandez coming on as a substitute to replace Ramos.
The team have yet to confirm the type of injury, but Ramos appeared to be holding his hamstring as he walked off the pitch.
He will undoubtedly undergo further tests to determine the severity of the ailment, and could be a threat to miss Saturday's Madrid derby when Atletico Madrid host Real.
