Everton defender Bryan Oviedo has undergone a successful operation on the double fracture to his leg.
The Costa Rica international broke his left tibia and fibula during Saturday's FA Cup fourth-round victory at Stevenage.
"Bryan's surgery was a big success," said Everton's head of medical services, Danny Donachie. "His tibia and his fibula were displaced [and] we weren't able to put them back into place until Monday."
He added: "He had surgery [on Monday] night when a rod was put through his tibia, which means he will come back stronger than before.
"It was a clean break and that means that there are no pieces of bone."
