The Reds’ 44-goal top scorer was forced off midway through the first half of Saturday’s Champions League final defeat to Real Madrid due to the problem he sustained in a tangle with 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 will head to Spain.
The Egyptian federation said Salah began his rehabilitation programme on Sunday, and was in “high spirits” and “determined to return quickly to the ranks of the team.”
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.
“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,” the 25-year-old wrote.
“Your love and support will give me the strength I need.”
