Thibaut Courtois could miss Real Madrid's game with Huesca on Sunday due to a injury picked up on international duty with Belgium.
The former Chelsea goal keeper was benched for Zinedine Zidane's first game back at the club, with Keylor Navas returning to the starting line up, and he trained alone on Friday as the squad prepares to welcome rock bottom Huesca.
Courtois, who started both game for Roberto Martinez's Red Devils in midweek, will be given up until close to kick off to prove his fitness to Zidane.
Navas and club captain Sergio Ramos trained alone on Thursday, but have since rejoined the main session.
Vinicius Junior and Dani Carvajal both stepped up their respective returns from injury, with the latter expected to return within two weeks, and Spanish international Lucas Vazquez is also back in action.
