Northern Ireland underage coach Stephen Frail has been named assistant manager at Dundee United.
The Glasgow native has been the manager for both the NI U17 and U19 sides since 2016 but leaves to join Mickey Mellon's coaching team at the newly-promoted Scottish Premiership side.
“I’m delighted for Stephen to get this opportunity," said Northern Ireland manager Ian Baraclough. "He has been a real asset for the development of our underage groups and the association as a whole.
“He joined on my first trip as the U21s manager to Estonia and was a huge help to me during that period.
“He has been an asset from day one and we wish him every success in this new and exciting role.”
The Irish FA will search for Frail's replacement 'in due course'.
Frail previously worked as Celtic's Development Squad Head Coach and U16 coach with the Scottish FA.
New Dundee United boss Mellon has previously managed Shrewsbury Town and Tranmere Rovers. He arrived last month to replace Robbie Neilson, who had led the club to the Scottish Championship title before leaving to join Hearts.
