Tuesday evening meeting
United will play Celtic Nation in the first round of this season's Cumberland Cup on Tuesday 11 September, kick off 7pm.
Full match details will be confirmed in due course.
Coach Eric Kinder said: "Some of the youth team will probably be involved in this one but I would imagine the manager will want his first team squad members used as well.
"It's a chance for the young lads who are used to step up to the plate and it will be a good game. We played Celtic Nation in pre-season and more than held our own, but I would think they will be a stronger side now.
"It's one I'm looking forward to because it will be a good test. Reserve wise we tend to organise games away at Middlesbrough, Celtic and Blackburn and it is those fixtures which I would rather play in.
"However, this is a game where the lads can go and pit themselves against top class non-league players and, in some cases, ex-professionals, so it'll be another good experience for them."
