The 26-year-old, who plays for Sion in Switzerland, ruptured his Achilles tendon during Nigeria's semi-final loss to Ghana on Thursday.

He was flown to South Africa on Friday evening where he went under the knife at the Rosebank Clinic in Johannesburg.

Super Eagles physiotherapist Ekundayo Ogunkunle, who accompanied Mohamed, told www.kickoffnigeria.com: "The operation was successful.

"The player is already wearing boots and they will manage him for three weeks or so before we come around to take him back to Nigeria."
