Northern Ireland boss Michael O'Neill has a final chance to look at his Euro 2016 squad options in Friday's friendly against Belarus at Windsor Park.
Wigan striker Will Grigg, 24, and Ross County forward Liam Boyce, 25, may be battling for one attacker spot in the squad along with outsider Billy McKay.
Full-backs Michael Smith, Lee Hodson and Daniel Lafferty also look to be in competition for one squad slot.
Friday's starting side will be familiar before O'Neill makes substitutions.
O'Neill will cut five names from his current 28-man squad when he announces his Euro 2016 hand in Belfast on Saturday.
The Northern Ireland manager admitted on Friday that he is "fairly fixed" about his selection but said players could still force themselves into his thinking.
"There's always the opportunity for someone. You have to prepare for every eventuality. There is the possibility of somebody getting injured although we don't want that to happen," O'Neill said.
Grigg's club form, as he scored 10 times in Wigan's final nine games, earned him a recall to O'Neill's squad after not featuring since the friendly against Qatar last May.
The Wigan striker's late-season goalscoring run saw him win the League One golden boot award, leading to a chant which has gripped social media as the Latics clinched promotion to the Championship.
Grigg may have edged ahead of Boyce in the Northern Ireland manager's thoughts even though the Ross County forward's campaign included winning the Scottish Premiership player of the month award for December.
Like Grigg, Burnley defender Lafferty made his Northern Ireland debut in the 6-0 hammering by the Netherlands four years ago.
Lafferty, who spent most of this season on loan at Oldham, has gone on to accumulate 13 caps and will hope to earn the nod over MK Dons full-back Hodson and Peterborough's Smith, who made his debut against Slovenia in March.
While O'Neill is certain to use the occasion to look at a number of his fringe players, the Northern Ireland boss will be determined to extend his team's record unbeaten run to 11 games.
Conor Washington's first international goal earned the Irish a 1-0 win over Slovenia in their last game in March, as the QPR striker produced a display which almost certainly secured his spot in France.
Unlike Slovakia, the Northern Irish's opponents in Trnava next week, Belarus are not France-bound having missed out in a qualifying group which featured Spain, Ukraine and the Slovakians.
