Everton's Bryan Oviedo out of Costa Rica squad
Everton midfielder Bryan Oviedo has pulled out of Costa Rica's friendlies against Oman and South Korea.
The Toffees have confirmed the 24-year-old is to remain on Merseyside to undergo a routine procedure to remove a small screw in his left leg which was inserted after an horrific break in January.
Oviedo made his competitive comeback with an hour-long appearance in the Capital One Cup defeat at Swansea last month and came on for the last 26 minutes of Sunday's loss against Manchester United - his first league appearance since January 20.
While Oviedo has returned to fitness other injuries are starting to pile up for manager Roberto Martinez.
John Stones was carried off on a stretcher at the weekend with suspected ankle ligament damage and is expected to be sidelined for at least a month while fellow defender Seamus Coleman has not played since mid-October because of a hamstring problem and, although he was named in the Republic of Ireland's squad to face Gibraltar in a Euro 2016 qualifier, he is unlikely to feature.
Forward Kevin Mirallas also has a hamstring strain which will keep him out until next month while midfielder James McCarthy will use the international break, having been left out of the Republic's squad, to recover from a thigh problem.
England midfielder Ross Barkley is progressing well after a knee operation but will not return until next month.
