Real Madrid confirms Ronaldo injury

Head coach Zinedine Zidane said he had no concerns that the injury could be a serious one, while Ronaldo himself took to Instagram to announce he was "all good" after the incident.

Ronaldo, who has not missed a minute of La Liga or Champions League football this season, is now likely to be rested for Saturday's short trip to face Rayo Vallecano.

Real Madrid have confirmed that Cristiano Ronaldo has suffered a thigh strain.

The Portugal star took himself off the pitch towards the end of the 3-0 win over Villarreal on Wednesday, clutching the back of his right leg.

Head coach Zinedine Zidane said he had no concerns that the injury could be a serious one, while Ronaldo himself took to Instagram to announce he was "all good" after the incident.

Madrid has now said that medical tests conducted this week have identified muscle damage, though it would not put an estimate on Ronaldo's recovery time.

"After the medical examinations conducted today [Friday] on our player, Cristiano Ronaldo, a the Hospital Universitario Sanitas La Moraleja, he has been diagnosed with a muscle strain in his right thigh," a club statement read.

"His progress will be monitored."

Ronaldo, who has not missed a minute of La Liga or Champions League football this season, is now likely to be rested for Saturday's short trip to face Rayo Vallecano.

He remains a doubt for the first leg of the Champions League semifinal with Manchester City at the Etihad Stadium on Tuesday.

Portugal coach Fernando Santos is understood to have spoken to Madrid, but is not concerned that Ronaldo's place at Euro 2016 could be jeopardised.

"I took care to learn of Ronaldo's condition," he told SportTV. "The information I have is that the probability of it being something very serious is small, thankfully."

Ronaldo leads the race for the Pichichi top-scorer prize in La Liga with 31 goals - one ahead of Barcelona's Luis Suarez - and has scored 47 in all competitions this season.
