Manchester United defender Jonny Evans will miss Northern Ireland's Euro 2016 qualifier against the Faroe Islands because of an ankle injury.
Evans sustained the injury during United's 5-3 defeat at Leicester City and will also be forced to sit out next week's game against Greece.
It is a blow for Northern Ireland manager Michael O'Neill as he looks to build on his side's impressive opening Euro 2016 qualifying success against Hungary in Budapest.

A brief statement from the Irish FA said: "Jonny Evans has been forced to withdraw from the Northern Ireland squad for the Euro 2016 qualifiers against Faroe Islands and Greece as the result of an ankle injury."
O'Neill had also been hoping to include Paddy McNair in his team but the Manchester United youngster picked up a hamstring injury during Sunday's win over Everton.
It is now thought that O'Neill will pick the same side that beat Hungary for Saturday night's Windsor Park clash with the Faroes. Evans was suspended for the 1-0 victory in Budapest.
Meanwhile, Faroe Islands goalkeeper Gunnar Nielsen is confident his side can secure a shock victory in Belfast.
The Motherwell shot-stopper is aware that Northern Ireland struggled against Luxembourg and Azerbaijan in their World Cup 2014 qualifiers and sees no reason why the Faroe Islands can't cause another upset.
He said: "We have been good in games at keeping a clean sheet in the first half but then maybe because we tire we concede goals in the second half. This time we will aim to keep the clean sheet for 90 minutes and make it hard for our opponents.
"It definitely gives us hope that in their last campaign Northern Ireland struggled against the smaller teams and of course we drew 1-1 with them a few years ago. We believe in ourselves that we can get a good result."
Northern Ireland are available at 1/1 to win the match 2-0 and can be backed at 1/1 to keep a clean sheet in the game.
