Liverpool forward Mohamed Salah will travel to Spain to undergo treatment on his injured left shoulder, the Egyptian Football Federation has announced.
The Reds' 44-goal top scorer was forced off midway through the first half of Saturday's Champions League final defeat to Real Madrid after spraining ligaments during a tangle with defender Sergio Ramos.
Salah tweeted on Sunday that he remained "confident" of being available for Egypt's World Cup campaign in Russia, and on Monday evening it was confirmed he would head to Spain.
The Egyptian federation said Salah began his rehabilitation on Sunday.
He will receive treatment in Spain, accompanied by the president of the Egyptian federation, the national team doctor and Liverpool medics.
"Mohamed Salah began his treatment programme on Sunday, when he confirmed in a telephone conversation with the technical and administrative staff of the team he was in high spirits and determined to return quickly to the ranks of the team," the federation said in a statement on its website.
Liverpool manager Jurgen Klopp feared the injury could rule Salah out of the World Cup, but the player wrote on Twitter: "It was a very tough night, but I'm a fighter. Despite the odds, I'm confident that I'll be in Russia to make you all proud.
"Your love and support will give me the strength I need."
