Arsenal's Ceadach O'Neill and Everton's Braiden Graham have retained their places in Northern Ireland's squad for the upcoming Nations League quadruple-header. The teenage pair were first called up by Michael O'Neill for June friendlies against Guinea and France, with O'Neill appearing in both matches. Defenders Dan Ballard, Paddy Mc Nair, Terry Devlin and Eoin Toal have returned after missing the June games, as have goalkeepers Bailey Peacock-Farrell and Conor Hazard, and striker Dion Charles.

Michael Forbes also earns a squad recall after his only previous cap against Finland in 2023. Liverpool's Conor Bradley remains absent due to knee surgery, joined by Preston's Ali Mc Cann and Aberdeen's Brad Lyons on the sidelines. After promotion from the third tier last year, Northern Ireland begin their 2026 Nations League B campaign with an away trip to Georgia on 25 September and conclude the window at home to the same opposition on 5 October.

In between, they face Hungary in Belfast and Ukraine in Slovakia. With four games in just 11 days, Michael O'Neill has called up 28 players—up from 23 in June—with goalkeepers Luke Southwood and Josh Clarke, plus striker Jamie Reid on standby.
