Arsenal's Ceadach O'Neill and Everton's Braiden Graham have retained their places in Northern Ireland's squad for the Nations League quadruple-header. The teenage pair were called up for the first time by Michael O'Neill for June friendlies against Guinea and France, with the Arsenal 18-year-old appearing in both games.

Defenders Dan Ballard, Paddy McNair, Terry Devlin and Eoin Toal have all returned to the squad after missing the June games. Goalkeepers Bailey Peacock-Farrell and Conor Hazard, as well as striker Dion Charles, are also back in the squad. Michael Forbes, a Dundee United defender, has also been included in the squad, having won his only previous cap against Finland in 2023.

The squad has been expanded to 28 players, with Michael O'Neill calling up additional players for the Nations League quadruple-header. Northern Ireland start their 2026 Nations League B campaign with an away trip to Georgia on 25 September.
