George Saville and Paddy McNair shared the minutes in Northern Ireland's 2-1 friendly defeat to the United States on Sunday.
Saville started at Windsor Park, and was one of four replaced on 61 minutes as Boro teammate McNair stepped into the fray.
The US had doubled their advantage minutes earlier via a contentious penalty, scored by Christian Pulisic, after a deflected Gio Reyna gave them the lead in the first half.
Niall McGinn pulled one back for the Green And White Army, but not enough to prevent the visitors coming away with victory.
All eyes turn to Wednesday for Ian Baraclough's side, and their next World Cup 2022 qualifier against Bulgaria in Belfast.
