The joint La Liga top scorer has missed Real's last two matches with a leg muscle strain and Mourinho said he will decide after training later on Tuesday whether to include his Portuguese compatriot in the squad.
Cristiano Ronaldo's participation in Real Madrid's Champions League last-16, second leg at home to Olympique Lyon on Wednesday still hangs in the balance, coach Jose Mourinho said.
The joint La Liga top scorer has missed Real's last two matches with a leg muscle strain and Mourinho said he will decide after training later on Tuesday whether to include his Portuguese compatriot in the squad.
Lyon, who have not lost to the nine-times European champions in seven meetings and knocked them out at the same stage last season, fought back to draw 1-1 in last month's first leg in France, although Real will be firm favourites to advance having won all their home games this term.
"I need to consult the medical department for a final opinion and to hear how the player himself feels, his final feelings in training," Mourinho said at a news conference at Real's vast facility outside Madrid.
"I am not going to wait until tomorrow," the former Inter Milan and Chelsea manager added.
"I don't like deciding the day of the match. I like to have everything clear in my head the day before. If he is fine he'll obviously play but we have to wait a bit longer to see."
Real hired Mourinho at the end of last season after he led Serie A side Inter to an unprecedented treble of domestic Italian league and cup and Champions League.
A 10th European crown has remained out of reach since their last title in 2002 and they have failed to progress to the quarter-finals of the continent's elite competition the past six seasons.
They limped out of last year's edition when Lyon snatched a 1-1 draw at the Bernabeu to progress 2-1 on aggregate.
Mourinho said Real should not obsess about winning their 10th title as even if they failed in the competition this season there was always next year.
"You have to remain calm," he said. "We have to fight hard to make it this year of course but if not then next. "It's not a serious problem. A serious problem is what is happening in Japan, not getting to the Champions League final."
