Portuguese doctor Nuno Campos, a former member of the medical team of his national football squad, has estimated superstar Cristiano Ronaldo could be out of action for 18 days if he has a muscle strain.

Ronaldo picked up the injury toward the end of a 3-0 win over Villarreal in the Spanish league on April 20, when he tried a volley inside the area and fell awkwardly. He seemed to be in pain and, after getting up, put his hand on the back of his right leg. Ronaldo walked off the pitch just before the final whistle, leaving the team with 10 men.

Without Ronaldo, Madrid' attacking potency reduced considerably with the Spanish giants unable to breakthrough a disciplined Manchester City. Worse, they at times looked blunt and were visibly lacking the creative spark and penetration that Ronaldo ensures.

Ronaldo is the leading scorer in Champions League this season with 16 strikes, way ahead of FC Barcelona's Luis Suarez (8). Media reports in Spain suggest he is suffering from a muscle problem.

"If the diagnosis really was a muscle strain, recovery lasts between 18 and 21 days. Twelve or 14 to heal completely and another five or seven days for muscle recovery," Campos told the Portuguese sports newspaper Record .

Campos explained that in the case the injury was just a muscle contracture, it would not prevent Ronaldo from facing Manchester City in the crucial second leg of the Champions League semi-finals.

The expert stressed that the most important response with muscle strain would be to not force Ronaldo to rejoin his team as soon as possible, as the player would then risk being unable to play in the Euro 2016 championship.

Meanwhile , in its report the sports daily AS suggested that Ronaldo would undergo "stem cell treatment" to try to recover in time for next week's game at the Santiago Bernabeu in Madrid.
