Jonny Evans is in contention to play a part in Northern Ireland's friendly with South Korea next weekend after joining up with the rest of his teammates on Monday afternoon.
The 30-year-old was seen as a doubt for Saturday's clash at Windsor Park after being withdrawn in club side West Bromwich Albion's 2-1 loss to Bournemouth because of illness.
Evans, who also sat out the previous weekend's loss to Leicester City with a similar problem, appears to be showing no ill effects as he remains a part of Northern Ireland's squad.
Albion boss Alan Pardew revealed ahead of the meeting with Bournemouth that Evans had trained as normal throughout the week.
Northern Ireland have climbed up to 24th in the latest FIFA rankings, meanwhile, despite missing out on a spot at the 2018 World Cup.
