Ahead of Northern Ireland's biggest game in almost 30 years, centre-back Jonny Evans could miss the crucial clashes with Greece and Finland after limping off in West Bromwich Albion's defeat to Crystal Palace.
Evans would be a massive miss for Northern Ireland
Evans, who joined the Baggies this summer, was unable to continue after picking up a hamstring injury in the 24th minute. Scans on Sunday after expected to reveal the true extent of the injury, and whether or not he will be able to feature on Thursday evening against the Greeks.
Some positive news did come out of the game, as Gareth McAuley played through the pain in the loss to complete 90 minutes. The veteran centre-half was originally doubtful for the two games after he sat out West Brom's 3-2 defeat to Everton on Monday night. McAuley will undergo a scan with Evans in a bid to shed more light on the situation.
The entire nation will be sweating over their fitness, as Michael O'Neill attempts to guide the Green and White Army to their first major tournament since the 1986 World Cup. McAuley has already scored three times in the qualifying campaign and is yet to miss a game. Evans, on the other hand, returned to the fold after almost two years out of the squad with injury and has featured in the last four qualifiers.
O'Neill already has personnel problems
Conor McLaughlin, Kyle Lafferty and Chris Baird are all banned for the penultimate qualifier, so to have both starting centre-backs available would be a massive boost. Craig Cathcart is expected to slot into defence in the place of McLaughlin, and the boss will want to avoid making too many changes to a sturdy defensive unit.
Northern Ireland need just one more win from their final two games to book their place at EURO 2016 in France. Draws in both games would also assure them of a spot at the finals, while Hungary failing to win either of their last two games means that O'Neill's side will make history.
