Spain right-back Dani Carvajal has been diagnosed with an injury to the peroneal tendon of his right ankle, Real Madrid said on Monday.

His club did not say for how long the player would be out, but Spanish newspaper AS has estimated two to three weeks.

Carvajal was forced off injured in the 41st minute of Real Madrid's 1-1 draw against Atletico Madrid on Sunday and replaced by Alvaro Arbeloa.

"I had an awkward foot movement, I was not comfortable and asked to be taken off," Carvajal said on Sunday. "I will have tests tomorrow and we will assess the injuries, but I am feeling positive, and getting better all the time."

He will not be available for Spain's European Championship qualifying matches against Luxembourg on Oct. 9 and against Ukraine on Oct. 10.

Spain coach Vicente del Bosque called up three injury replacements for Carvajal, Inigo Martinez and Bruno Soriano.

Mario Gaspar from Villarreal will join the squad, as will Xabier Etxeita and Mikel San Jose, both of Athletic Bilbao.

Real Sociedad defender Martinez sustained a muscle injury in his left leg and Villarreal midfielder Soriano has been ruled out with a knee injury.

Spain top Group C and can clinch qualification with a win against Luxembourg.
