Barcelona midfielder Andrés Iniesta will be out four matches after medical tests performed on Sunday proved that he had suffered a strain in his right calf, Alberto Martínez of AS reported Monday morning.
Iniesta, 30, left the pitch in the 72nd minute of Barcelona's loss to Real Madrid on Saturday.
His injury was a non-contact injury, which gave Barça's medical team concern that he had a muscular injury, according to the report.
On Sunday morning, Iniesta tweeted that he would begin his recuperation to be ready as soon as possible for Barcelona.
Empiezo mi recuperación para estar lo antes posible con el equipo!! Força Barça!— Andrés Iniesta (@andresiniesta8) October 26, 2014
Barcelona has yet to officially confirm the extent of the injury, but it is likely that Iniesta will miss the Copa Catalunya final against Espanyol on Wednesday, league games against Celta Vigo on Nov. 1 and Almería on Nov. 8, and a Champions League match with Ajax on Nov. 5.
He is also likely to miss Spain's Euro 2016 qualifier against Belarus on Nov. 15 and an international friendly against World Cup champion Germany on Nov. 18.
Though he has encountered problems with his right calf in the past, this is Iniesta's first such issue this season. Including Saturday's match against Real Madrid, the midfielder has played seven league matches and ten in total this season.
His recovery will likely be aimed to prepare him for Barcelona's Nov. 22 match with La Liga side Sevilla, currently in second place to Barça on goal difference.
