Cristiano Ronaldo remains a doubt for Real Madrid's La Liga game against Athletic Bilbao on Sunday evening at the Estadio Santiago Bernabeu.
Ronaldo, 29, suffered some tough treatment from his markers during Wednesday's 2-1 Champions League win at Ludogorets, receiving medical attention late in the game after being kicked in the back of his lower right leg by the Bulgarian side's Madagascar international Anicet Abel.
Blancos coach Carlo Ancelotti played down the incident after the game, telling his postmatch news conference that "it was a painful knock, but nothing serious."
However, Ronaldo himself told reporters in the stadium's mixed zone that he did not appreciate being kicked from behind in such a painful area.
This immediately led to fears that Madrid could be without their top scorer -- who has 10 goals in his first five La Liga appearances of the season -- for Sunday's game against Athletic.
However, fears were eased when the Portugal captain was named in his country's squad for their upcoming friendly against France and Euro 2016 qualifier against Denmark.
A Madrid club statement released on Friday revealed that Ronaldo had yet to return to full training with his teammates, while also saying that Gareth Bale and Fabio Coentrao had not taken part in Friday's morning session.
"Real Madrid continued their preparations for the match against Athletic, which they play this Sunday at the Santiago Bernabeu," the statement said.
"Ancelotti placed an emphasis on working with the ball in a training session that saw Cristiano Ronaldo do running alone on the pitch at Ciudad Real Madrid. Bale and Coentrao did work indoors at Madrid's training facilities, while Jese and [Sami] Khedira continue with their recovery processes."
Ronaldo's last appearance against Los Leones saw him red-carded for raising a hand during a confrontation with Athletic's Carlos Gurpegi and Ander Iturraspe, and being given a three-match ban in total after making a gesture to the officials as he left the field.
