Real Madrid have included Toni Kroos and Luka Modric in their 24-man squad for Tuesday's Champions League clash with Paris Saint-Germain.
The midfielders have been battling to be fit for the last-16 second leg in the French capital and both missed Saturday's 3-1 LaLiga win over Getafe.
Kroos, who particularly impressed in Madrid's 3-1 first-leg win, has been struggling due to a knee ligament sprain, while Modric has a hamstring problem.
However, both returned to training on Sunday and will travel to France for the showdown with Unai Emery's men.
Speaking on Saturday, Zidane said he was unsure if they would be fully fit but was not worried about the prospect of their absence.
