Real worried about Ronaldo
The striker scored Real`s opener in their 2-1 win on Tuesday, but limped out of the match on 50 minutes.
Initial fears of a recurrence of his old knee trouble were swiftly allayed, but the calf problem in his left leg is clearly causing concern.
Real`s chief medical officer Alfonso Del Corral is set to run more stringent tests on Ronaldo on Wednesday and Thursday, but said the Brazilian World Cup winner is a 'serious doubt' for the return leg.
Ronaldo will definitely miss the weekend Liga encounter with struggling Recreativo Huelva, and his absence will put a strain on Vicente Del Bosque`s resources as Raul is still on the sidelines.
