Gareth Bale did not train with the rest of his teammates on Wednesday at Real Madrid's training ground in Valdebebas.
The Welshman has returned from international duty with a knee discomfort and worked out in the gym instead.
The forward played in Wales' 1-0 win over Bulgaria on Sunday and has returned to his club with an issue, even though he didn't appear to pick up any injury during the game.
Bale is awaiting a meeting with Los Blancos to find a solution regarding his future, which is extremely uncertain.
Meanwhile, Zinedine Zidane prepared a very demanding session, although he was still without some of the club's internationals, such as Eden Hazard, Luka Jovic, Raphael Varane and Ferland Mendy.
