MADRID -- Real Madrid striker Ronaldo will be sidelined for three weeks after suffering a recurrence of a calf injury in his right leg, the Primera Liga club said on Monday.
The Brazil international, who sustained the original injury when he resumed training after the winter break, returned to action against Villarreal on Sunday after missing his side's King's Cup tie against Athletic Bilbao last Tuesday.
He only survived 33 minutes before limping off. The game ended goalless.
Ronaldo has had a difficult season with Real so far, missing all six of their Champions League matches because of injury and suspension, and struggling for fitness after an ankle injury he collected against Atletico Madrid in October.
Ronaldo misses his side's King's Cup second leg tie against Bilbao on Thursday and could miss the quarter-finals if Real progress, as well as up to three league games.
