Real Madrid manager, Zinedine Zidane, has said he is becoming frustrated by their growing injury list, after Luka Modric and Marcelo were forced off against Malaga on Saturday.
Marcelo came off in the first half and was replaced by Isco, prompting Lucas Vazquez to move into right-back.
Modric did not finish the game, as he was replaced by Mateo Kovacic.
Madrid already have Dani Carvajal, Gareth Bale, James Rodriguez and Pepe out with injury, ahead of Wednesday’s Copa del Rey quarter-final second leg at Celta Vigo.
“Luka has an issue, some discomfort,” Zidane told reporters after the match.
“We hope it is not serious. We will see on Sunday with a scan. We don’t know the exact problem yet.
“Marcelo’s injury is more complicated and they will both undergo more tests.
“Coentrao has a problem too, and the Castilla team are not here this weekend, otherwise I would have put in one of the youngsters.
“Danilo felt discomfort after Friday’s training and in the morning wasn’t feeling well so we decided to rest him. I am a bit upset with the injuries. My mind is a bit blown. We have a big game Wednesday and injuries are screwing it up.
“A lot of the season is still left and like I always say, we will be needing every player.”
