Northern Ireland have received a boost with the news that Jonny Evans will be available to face Luxembourg on Tuesday.
It had been feared that the defender may have to pull out of Michael O'Neill's squad after picking up a knock in Friday's 2-0 defeat by Russia.
Evans had an ankle operation in the summer and has yet to play for Manchester United this season.
He admitted over the weekend that he had played through the pain against Russia, but was able to train on Sunday and has now been passed fit.
Northern Ireland will be looking to get their World Cup qualifying campaign up and running with a win over Luxembourg at Windsor Park.
Luxembourg will have other ideas, though, after taking the lead in their opening match against Portugal before narrowly losing 2-1.
