Cristiano Ronaldo suffered an injury in their league match against Barcelona in Camp Nou on Sunday. The Portuguese star is yet to be scanned as the extent of the injury is still uncertain.

Ronaldo took a knock in the 14th minute when he tapped in Karim Benzema's header to equalize the score 1-1. He was substituted in the 45th minute with Marco Asensio coming on for him.

Real went on to secure a 2-2 draw without Ronaldo, as Gareth Bale struck in the 72nd minute after Lionel Messi's superb individual effort put 10-man Barca ahead in the 52nd minute.

Sergi Roberto had been sent off at the end of the first period after Luis Suarez opened the scoring in a pulsating, and highly controversial, El Clasico.

Ronaldo's injury is the main concern for the French manager as the Champions League final appears closer than ever but was confident that his talisman will be fine by the final which is on May 26.

"How long he will need I cannot tell you but for him, it is a small problem," Zidane said afterwards.

"We'll see tomorrow after the tests, what we have to do is see the damage done to the ankle. He is a little worried because his ankle is a bit swollen but he said it was only minor.

Marca reported that the extent of the injury has become clear and it is certain that the Portuguese will not miss the final and reportedly will miss the game against Sevilla on Wednesday.

Ronaldo has been in scintillating form and him missing the Champions League will be a major loss. Real will definitely try to help the talisman to recover in time for the final.
