Real Madrid CF attacker Cristiano Ronaldo may miss his side's UEFA Champions League round of 16 second leg against Olympique Lyonnais after being ruled out for two weeks with a left thigh injury.

The 26-year-old Portugal winger felt soreness in his left leg after completing his hat-trick in Thursday's 7-0 Liga triumph over Málaga CF in the Spanish capital, with tests subsequently showing that he will be sidelined for ten to 15 days.

Midfielder Fernando Gago, meanwhile, is certain to sit out the Lyon match after suffering a right adductor tear during Friday's training session. The 24-year-old Argentinian international – who has been limited to seven appearances in all competitions this term – will be unavailable for three weeks.

Madrid coach José Mourinho must now prepare for the upcoming league encounters with Real Racing Club and Hércules CF, as well as for Lyon's visit to the Santiago Bernabéu on Wednesday 16 March, without the team's 27-goal Liga top scorer Ronaldo.
