Newcastle United defender Jamal Lewis is set to undergo a scan on an Achilles 'niggle' and will miss Northern Ireland's upcoming clash with Norway.
The 22-year-old has not travelled with the squad to Oslo for Wednesday night's Nations League tie, and is the only definite absentee for the contest.
Lewis has completed 210 minutes in his last two international outings with the Euro 2020 qualifying play-off semi-final victory over Bosnia and Herzegovina on Thursday night and Sunday's 1-0 home defeat to Austria.
Northern Ireland boss Ian Baraclough insists it is a precautionary measure and one the player or fans should not 'worry about'.
He said: "The only one who isn't travelling is Jamal Lewis.
"He's gone to have a scan on his ongoing Achilles niggle, but it's nothing to worry about. It's improving.
"He mightn't be able to play the two games so quickly, so it's something I felt Newcastle had in mind for the player anyway."
It is the third international match in seven days for Northern Ireland, and Baraclough admits it is a "balancing act" to ensure his team is rotated yet remains competitive.
He added: "We're going to be sensible. We will make it competitive, but one or two players will get starts that haven't started the two previous games as well.
"It's important I look at these players and it's important they get game time as well.
"We're not fortunate enough to have a squad of players that you go and play three totally different teams and make massive changes like an England or Germany or Spain.
"There has to be a certain amount of continuity because we don't have that amount of depth in our country.
"We'll be prepared and the players know it's the last game now before (the Euro 2020 qualifying play-off final against) Slovakia so it's a chance to impress in that respect."
