Ronaldo a doubt for Madrid derby - press
The 28-year-old picked up a thigh problem during Wednesday's crushing 4-1 Champions League semi-final, first leg defeat at Borussia Dortmund and did barely five minutes of jogging on Friday before returning to the indoor gym at Real's training complex, several Spanish media said.
It means Ronaldo's participation against Atletico on Saturday is in doubt, particularly with a second leg against Dortmund to come on Tuesday.
Real need to get a result in the derby to maintain their hold on second place in La Liga with their city rivals just three points behind in third.
Ronaldo, the top scorer in the Champions League this season with 12 goals, had been thought to be certain to start against Dortmund in the Bernabeu but Friday's news has caused some to question that theory.
"At Real they said the Portuguese was sure to play in the semi-final second leg but Friday's training session has instilled some doubt," said Marca on their internet site.
