The Everton left back shattered his leg in an FA Cup clash with Stevenage in January, and was told he would not play until next season at the earliest.
But the Costa Rican international has made a recovery that manager Roberto Martinez has described as ‘phenomenal’ and is on course to face England in the Group D clash in Brazil.
“We sent him to Costa Rica with the national team and they will assess him. But the specialist saw him this week before he went away, and feels he can make the World Cup, which is incredible.
“He’ll be in Costa Rica for two weeks, the specialist is going over from London and we’re working together to see if we can get him fully fit. It’s an incredible opportunity for him.”
Oviedo earned cult hero status amongst Toffees fans after striking the winner against Manchester United at Old Trafford earlier in the season, and Martinez reckons he deserves more praise for the bravery he has shown in his recovery.
“Bryan is an incredible boy and a really quick healer, whose mentality and approach are unbelievable,” he said.
“He has that huge goal of the World Cup and is a great example for anyone. I know for sure he will be fine for pre-season, but if we can get him okay for the summer, it will be incredible.
“I would encourage that, he deserves it. And I think we can get a better player at Everton if we can get him to the World Cup. Physically he’s a machine and I would never have a concern about that.”
