Real Madrid's Brazilian midfielder Casemiro sprained his right ankle over the weekend during the 4 - 2 La Liga win against Celta Vigo, the club announced in a statement Monday.
Casemiro was forced off the field early in Sunday's away game and underwent medical tests that revealed the extent of the injury, reports Efe.
"(Casemiro) has been diagnosed with a sprained right ankle.
His recovery will continue to be assessed, " Real Madrid said in a statement.
Also injured was Spanish defender Nacho Fernandez, who was replaced in the 71st minute, and suffers "a dislocation of the internal collateral ligament of the right knee, " Real Madrid announced, without providing details on his estimated recovery time.
