Lazio midfielder Ogenyi Onazi is facing months on the sidelines with a leg fracture.
The 21-year-old was stretchered off after a tackle from France's Blaise Matuidi during Nigeria's 2-0 defeat to Les Bleus in the last-16 tie in Brasilia.
Onazi was taken to a nearby hospital, and tests confirmed he has a fractured tibia and fibula in his left leg.
The Super Eagles star tweeted a photograph of his left leg in a cast and included a message that said: "Thanks to everyone for your prayers, will be fine by his grace.
"God Bless Nigeria."
