Real Madrid defender Jesús Vallejo will be out for the next month with a hamstring problem, the club confirmed on Saturday.
Vallejo was taken off injured during Madrid's 1-0 Copa del Rey win against Leganes in midweek.
"Following the tests carried out today on our player Jesús Vallejo at the Sanitas La Moraleja University Hospital, he has been diagnosed with a muscular injury to his right hamstring," Madrid said.
"His recovery will continue to be assessed."
