Real Madrid have a slight injury doubt over Cristiano Ronaldo ahead of this weekend\'s La Liga clash with Sporting Gijon. A statement on Real\'s website confirmed the forward had suffered a sprain and contusion to his left ankle and sat out today\'s training session. Ronaldo picked up the injury in a challenge with Luis Perea during Saturday\'s 4-1 win over Atletico Madrid. The Portuguese scored two penalties in the victory and was able to complete the full 90 minutes.
