Republic of Ireland midfielder Jason McAteer has been passed fit to face Cameroon on Saturday.
The 30-year-old is expected to start in the Group E game in Niigata after recovering from a knee injury that at one stage threatened his participation in the finals.
McAteer picked up a knee injury in Ireland's 2-1 friendly defeat against Hiroshima last Saturday - following a bad tackle by former Cameroon international Bilong.
The injury was initially feared to be damaged knee ligaments but scans revealed the Sunderland player had only suffered from bad bruising.
McAteer will win his 48th cap for the Irish if he is given the go-ahead to start by manager Mick McCarthy.
The Football Association of Ireland (FAI) has confirmed Fifa has told them they will not be able to bring in a replacement for Roy Keane as he was not injured when he left the squad.
