Juventus coach Claudio Ranieri fears Jorge Andrade will be sidelined for the rest of the season after suffering a serious knee injury.
The defender tore a ligament in his left knee during Juventus' 2-2 draw with Roma on Sunday.
Andrade is set to undergo tests to assess the full extent of the damage, but Ranieri is expecting the worst.
"I am really saddened for Andrade," said Ranieri.
"I fear I will lose him for the entire season and I will have to find an alternative."
Andrade has made three appearances for Juventus since leaving Deportivo La Coruna in the summer.
